Abstract
Description
[0001] Ketoreductases (KREDs, also known as "alcohol dehydrogenases" ADHs, or "carbonyl reductases") catalyze the reduction of aldehydes and ketones to the corresponding primary and secondary alcohols, respectively. These enzymes can also catalyze the reverse reaction, i.e., the oxidation of primary and secondary alcohols to the corresponding aldehydes and ketones, respectively.
[0002] The reduction of ketones to secondary alcohols is of great interest for industrial applications, as prochiral carbonyl compounds are stereoselectively reduced to chiral alcohols. In some industrial applications, the stereoselective conversion of secondary alcohols to ketones for the chiral resolution of racemic compounds is also desired, e.g., to allow the separation of enantiomers. In industrial applications, the enzymatic oxidation of primary alcohols to aldehydes and the enzymatic reduction of aldehydes to primary alcohols are generally considered to be of lower relevance, but can also be catalyzed by KREDs. The use of the same KRED in either the oxidation or the reduction reaction can be influenced by adjusting the chemical equilibrium of the enzymatic reaction.
[0003] The KRED-catalyzed reduction requires a reduced cofactor as electron donor. Some KREDs use reduced nicotinamide adenine dinucleotide (NADH) as cofactor, other KREDs use reduced nicotinamide adenine dinucleotide phosphate (NADPH), and some ketoreductases can use both NADH and NADPH. The KRED-catalyzed oxidation requires a corresponding oxidized cofactor as electron acceptor. For this reaction, KREDs use oxidized nicotinamide adenine dinucleotide (NAD + ) or oxidized nicotinamide adenine dinucleotide phosphate (NADP + ) or both NAD + and NADP + .
[0004] KREDs are ubiquitous enzymes found in all kingdoms of life. Known commercially available KREDs are from horse liver (HLADH), baker's yeast (YADH), and bacteria, such as Thermoanaerobium brockii (TBADH) and Lactobacillus kefir (LKADH).
[0005] Based on their sequence identity and biochemical properties, KREDs can be divided into different protein families. Members of the SDR-family (short-chain-dehydrogenases / reductases) exhibit short-chain enzymes, which do not contain any metal ions. In contrast, members of the MDR-family (medium-chain-dehydrogenases / reductases) exhibit medium-chain enzymes, which depend on Zn 2+ . Another group of KREDs exhibits long-chain enzymes, which depend on Fe 2+ . (For review: K. Drauz, H. O. May, Enzyme Catalysis in Organic Synthesis, Wiley VCH, Weinheim, 2012).
[0006] For industrial applications it is desirable to use KREDs with high specific activity and stereoselectivity. Another important criterion for the industrial use of KREDs is long process stability, which is usually linked to high stability at high temperatures and high solvent stability. If the substrate is already chiral, it is also desirable to use KREDs with high stereodirecting properties.
[0007] Improvements of enzymes can be achieved by enzyme engineering. This technology involves the development of variants of a starting enzyme with improved properties (for review: S. Lutz, U. T. Bornscheuer, Protein Engineering Handbook, Wiley VCH, Weinheim, 2009).
[0008] The in vitro use of KREDs in reduction processes requires a regeneration system for NAD(P)H. Common regeneration systems are glucose dehydrogenase (GDH) or formate dehydrogenase, which are used in combination with KREDs. The cofactor regeneration can also be performed by the KRED itself through the concomitant oxidation of a cosubstrate, usually a primary or secondary alcohol, such as isopropanol to acetone. The concomitant use of KREDs as reduction catalysts with a cofactor regeneration system requires the simultaneous acceptance of a ketone substrate and a cosubstrate for the cofactor regeneration. The choice of the specific cosubstrate can depend on the specific activity of the KRED for this cosubstrate and the stability of the KRED under the specific cofactor regeneration conditions.
[0009] Besides the reversible reduction of aldehydes, there are some reports about ketoreductases catalyzing the oxidation of aldehydes to the corresponding acids. However, this reaction is considered as a side reaction rather than the main reaction (for review: K. Drauz, H. O. May, Enzyme Catalysis in Organic Synthesis, Wiley VCH, Weinheim, 2012).
[0010] Examples for industrial applications of KREDs to produce valuable compounds are the reduction of 1-phenyl-2-propanone by Rhodococcus erythroplis KRED, the reduction of ethyl acetoacetate by Lactobacillus brevis KRED or the reduction of ethyl 6-benzyloxy-3,5-dioxo-hexanoate by a KRED from Acinetobacter calcoaceticus (for review: A. Liese, K. Seelbach, C. Wandrey, Industrial Biotransformations, Wiley VCH, Weinheim, 2006).
[0011] Even though a large number of KREDs for asymmetric reduction of a ketone are described in the literature, only a few KREDs are used in patent processes. Many processes contain a ketoreductase from Lactobacillus kefiranofaciens (LKADH) or variants thereof.

[0013] Protein database online, accession number: WP_022887115, relates to a Glaciibacter superstes short-chain dehydrogenase.
[0014] However, the prior art ketoreductases are unsatisfactory in all respects and there is a need for ketoreductases having advantages over conventional ketoreductases, in particular advantages in terms of high process stability and good cofactor reactivity in the industrial production of chiral alcohol compounds, respectively. In this respect, high process stability in industrial applications can include chemical and physical stability and enzymatic activity under aqueous, non-aqueous and / or biphasic systems, and / or at high substrate concentrations and / or at high temperatures and / or in the presence of water-miscible solvents and / or a broad pH range of 4-11 and / or on solid supports (i.e. when immobilized) and / or under high shear forces (e.g. by stirring, suction, membrane filtration preparation). Other factors, such as substrate selectivity, K M , specific activity, stereoselectivity, stereospecificity, diastereoselectivity, regioselectivity, substrate inhibition, product inhibition, other factors such as inhibition by crude extract components, substrate contaminants or byproducts, and recombinant soluble expression capability in suitable hosts can play an important role. When the substrate is a chiral substrate, i.e. already contains one or more chiral centers and / or axes of chirality, it can be desirable that the stereoselectivity of the enzymatic reduction of the prochiral carbonyl group contained in said chiral substrate is essentially not influenced by said one or more chiral centers and / or axes.
[0015] It is an object of the present invention to provide improved ketoreductases.
[0016] The subject matter of the present patent application has solved this problem.
[0017] The present invention provides novel ketoreductases, in particular engineered ketoreductases exhibiting improved properties compared to wild-type enzymes, preferably wild-type ketoreductases of SEQ ID NO: 2.

[0019] The ketoreductases of the present invention comprise an amino acid sequence which is a certain homology to the amino acid sequence of SEQ ID NO: 2. This means that the ketoreductases of the present invention can comprise said amino acid sequence as a subsequence of its total amino acid sequence, or the ketoreductases of the present invention can essentially consist of said amino acid sequence. When the ketoreductases of the present invention comprise said amino acid sequence as a subsequence of its total amino acid sequence, said total amino acid sequence can be extended at the N- and / or C-terminus of said subsequence, i.e. can comprise further amino acid residues. Such extensions can be advantageous, for example, when the ketoreductases are immobilized on a solid support, for example for purification purposes.
[0020] In the sense of the present application, the homology is preferably calculated as identity using BLASTP (Stephen F. Altschul, Thomas L. Madden, Alejandro A. Schaffer, Jinghui Zhang, Zheng Zhang, Webb Miller, and David J.

[0036] - high stereospecificity, and / or
[0037] - high stability in various solvents, optionally containing a co-substrate such as isopropanol.
[0038] For the purpose of illustration, stereoselectivity is the property of a chemical reaction in which a single reactant forms an unequal mixture of stereoisomers during the non-stereospecific creation of a new stereocenter or during the non-stereospecific conversion of an already existing stereocenter. Selectivity usually arises from differences in steric and electronic effects in the mechanistic pathways leading to different products. Preferably, the conversion of a substrate to a chiral product under the catalysis of the ketoreductase of the application provides the desired chiral product in an enantiomeric excess of at least 50% ee, more preferably at least 75% ee, still more preferably at least 90% ee, still more preferably at least 95% ee, even more preferably at least 97% ee, most preferably at least 98% ee, in particular at least 99% ee.

Examples of such ketoreductases include an amino acid sequence according to SEQ ID NO: 17, 21, 26, 38, 40, 62, 72, 73, 81, 83, 86, 92, or 93, preferably SEQ ID NO: 17, 21, or 73, more preferably SEQ ID NO: 17.
[0128] In some embodiments, the ketoreductase of the application is capable of oxidizing a secondary alcohol to the corresponding ketone, e.g., 2-butanol to 2-butanal.
[0129] In some embodiments, the ketoreductase of the application is capable of oxidizing a primary alcohol to an aldehyde compound, e.g., 1-heptanol to 1-heptanal.
[0130] In some embodiments, the ketoreductase of the application is capable of oxidizing an aldehyde compound to a carboxylic acid.
[0131] Preferably, the ketoreductase of the application is capable of oxidizing a co-substrate for cofactor regeneration with a high specific activity, preferably with a specific activity of 0.1-100 U / mg, more preferably with a specific activity of 1-50 U / mg, most preferably with a specific activity of 10-12 U / mg of the lyophilisate of the ketoreductase. In the sense of the present application, the co-substrate which is converted, preferably oxidized, by the ketoreductase of the application and which accompanies the conversion, preferably reduction, of the ketone substrate is a primary or secondary alcohol.
[0132] The co-substrate can be selected according to the specific activity for cofactor regeneration, preferably selected from the group consisting of isopropanol, 2-butanol, 2-pentanol, 2-hexanol and 2-heptanol. Preferably, the ketoreductase of the present application converts isopropanol to propanone with a high specific activity. The ketoreductase lyophilisate can be obtained, for example, by cell disruption as described in Example 2 (see below) followed by freeze-drying of the crude extract.
[0133] To determine the oxidative activity of a given co-substrate, the ketoreductase of the present application is incubated in a buffer containing 20% co-substrate, for example isopropanol, and a cofactor, for example 0.25 mM NAD(P), preferably at 30°C. The oxidative activity is determined by measuring the decrease in absorbance at 340 nm resulting from the reduction of NAD(P). The ketoreductase having the amino acid sequence of SEQ ID NO: 2 exhibits a specific activity of 10.6 U / mg ketoreductase lyophilisate for the oxidation of isopropanol under the specified conditions.
[0134] Preferably, the ketoreductase of the present application exhibits a high specific activity in a co-substrate, preferably in isopropanol, 2-butanol, 2-pentanol, 2-hexanol and / or 2-heptanol. Preferably, after pre-incubation of the ketoreductase in 50% aqueous co-substrate, preferably isopropanol, for 48 hours at 30°C, the ketoreductase exhibits at least 1%, more preferably at least 10% or at least 20%, still more preferably at least 30% or at least 40%, still more preferably at least 50% or at least 60%, even more preferably at least 70% or at least 80%, most preferably at least 85% or at least 90%, in particular at least 95% or at least 99%, residual activity relative to its activity prior to pre-incubation with the co-substrate. In this respect, residual activity in the sense of the present application describes the remaining ketoreductase activity of the enzyme after pre-incubation with a co-substrate compared to the activity after pre-incubation without the co-substrate. To determine the stability in a co-substrate, including for example isopropanol, the ketoreductase of the present application is pre-incubated in a buffer, preferably at 30°C in 50% co-substrate, for example isopropanol, at pH 9 for 48 hours, and the enzymatic activity of the ketoreductase is compared to the enzyme pre-incubated without the co-substrate. The residual activity of the ketoreductase of the present application is 100% when both enzymatic activities are identical; i.e. there is no loss of activity compared to the activity without pre-incubation with the co-substrate. The ketoreductase having the amino acid sequence of SEQ ID NO: 2 exhibits a residual activity of 100% under the described conditions.
[0135] The efficient conversion of co-substrates by the ketoreductase and the stability of the ketoreductase in the co-substrate are of particular relevance for the establishment of efficient industrial processes for the reduction of ketone or aldehyde substrates to secondary or primary alcohols. The stability of the ketoreductase of the present application in co-substrates and its ability to convert the co-substrates of the present application are also relevant for the reverse conversion of primary and secondary alcohols to aldehyde and ketone substrates.
[0136] In some embodiments, the ketoreductase of the application exhibits increased specific activity, temperature stability, and / or stereoselectivity when engineered with SEQ ID NO: 2.
[0137] The increased specific activity of the application relates to the specific activity of the engineered ketoreductase being higher than the specific activity of the non-engineered ketoreductase of SEQ ID NO: 2. Preferably, the specific activity is at least 10%, or at least 50%, or at least 100%, or at least 1.5-fold, or at least 2-fold, or at least 3-fold, or at least 5-fold, or at least 10-fold, or at least 20-fold, or at least 50-fold, or at least 100-fold, or at least 200-fold, or at least 300-fold, or at least 500-fold, or at least 700-fold, or at least 1000-fold, or at least 10,000-fold, or at least 100,000-fold higher than the specific activity of the non-engineered ketoreductase. The increased specific activity can also mean that the engineered ketoreductase does exhibit a particular activity for a desired substrate, whereas the non-engineered ketoreductase does not have significant activity for said substrate.
[0138] The increased temperature stability of the application relates to the engineered ketoreductase having a higher residual specific activity after incubation at 30 °C for 48 hours compared to the non-engineered ketoreductase of SEQ ID NO: 2. Alternatively, the increased temperature stability of the application can relate to the engineered ketoreductase having the same residual specific activity compared to the non-engineered ketoreductase after incubation at a higher temperature for the same time or at the same temperature for a longer time.
[0139] The stereoselectivity of the application relates to the enantiomeric excess of the product provided by the engineered ketoreductase being higher than the enantiomeric excess of the product provided by the non-engineered ketoreductase of SEQ ID NO: 2. Preferably, the enantiomeric excess provided by the engineered ketoreductase is increased by at least 0.1% ee, at least 0.5% ee, at least 1% ee, at least 2% ee, at least 3% ee, at least 5% ee, at least 7% ee, at least 10% ee, at least 20% ee, at least 30% ee, at least 40% ee, at least 50% ee, at least 60% ee, at least 70% ee, at least 80% ee, at least 90% ee, at least 95% ee, at least 97% ee, at least 98% ee, or at least 99% ee compared to the non-engineered ketoreductase. The increased stereoselectivity can also mean that the engineered ketoreductase does exhibit a particular stereoselectivity for a desired chiral product, whereas the non-engineered ketoreductase does not have significant stereoselectivity for said chiral product.
[0140] The increased specific activity of the engineered ketoreductase compared to the non-engineered ketoreductase of SEQ ID NO: 2 is preferably determined under standard reaction conditions, typically at 30°C in an aqueous buffer solution containing the substrate, the co-factor, optional supplements and the ketoreductase. The buffer is preferably selected from 10-200 mM Tris / HCI, pH 7-9, 10-200 mM sodium phosphate / NaOH, pH 6-8, or 10-200 mM triethanolamine / HCI, pH 7-9, containing 2 mM MgCI2. The co-factor NADH is preferably added to a final concentration ranging from 0.05-10 mM. The substrate is preferably added to a final concentration ranging from 5 mM to 1 M, the substrate preferably being selected from ethyl-4-chloro-3-oxo-butyrate, 1-(4-chloro-phenyl)ethanone, 1-(2-methoxyphenyl)ethanol, tert-butyl (5R)-6-cyano-5-hydroxy-3-oxo-hexanoate, N,N-dimethyl-3-keto-3-(2-thienyl)-1- ketopropylamine, ethyl secodione (ethyl-3-methoxy-8,14-seco-steran-1,3,5(10),9(11)- tetraen-14,17-dione), tert-butyl (5S)-6-chloro-5-hydroxy-3-oxohexanoate, and N- monomethyl-3-keto-3-(2-thienyl)-1-ketopropylamine, phenyl-(2-pyridyl)-methanone, ethyl 3-oxo-3-phenyl-propionate, 3-quinuclidinone, 2-butanal and 1-heptanal. Optional further supplements are preferably selected from 1-5% Triton X-100 (v / v) and 0.5-10% DMSO (v / v). The ketoreductase is preferably added as a crude extract supernatant. The crude extract is obtained by disrupting the expression host containing the ketoreductase, followed by centrifugation to separate the cell debris and the ketoreductase containing crude extract supernatant. The specific activity is determined by measuring product formation, consumption of reduced co-factor NADH and / or substrate consumption. In case the specific activity is determined by measuring product formation or substrate consumption, a co-factor regeneration system (isopropanol or GDH / glucose) can be applied in the standard reaction; in case the specific activity is determined by measuring consumption of reduced co-factor NADH, no co-factor regeneration system is applied. In case a co-factor regeneration system is applied, the reduced co-factor NADH can be regenerated by the co-factor regeneration system from oxidized co-factor NAD TM X-100 (v / v) and 0.5-10% DMSO (v / v). The ketoreductase is preferably added as a crude extract supernatant. The crude extract is obtained by disrupting the expression host containing the ketoreductase, followed by centrifugation to separate the cell debris and the ketoreductase containing crude extract supernatant. The specific activity is determined by measuring product formation, consumption of reduced co-factor NADH and / or substrate consumption. In case the specific activity is determined by measuring product formation or substrate consumption, a co-factor regeneration system (isopropanol or GDH / glucose) can be applied in the standard reaction; in case the specific activity is determined by measuring consumption of reduced co-factor NADH, no co-factor regeneration system is applied. In case a co-factor regeneration system is applied, the reduced co-factor NADH can be regenerated by the co-factor regeneration system from oxidized co-factor NAD + Alternative.
[0141] The increased stereoselectivity of the engineered ketoreductase compared to the non-engineered ketoreductase of SEQ ID NO: 2 is preferably determined under standard reaction conditions as described above for determining the increased specific activity. Chiral analysis is applied to analyze the product formed in the reaction.
[0142] The increased temperature stability of the engineered ketoreductase compared to the non-engineered ketoreductase of SEQ ID NO: 2 is preferably determined by incubating the crude extract containing the ketoreductase for 15 minutes at a given temperature in a PCR cycler, preferably at a temperature at which the non-engineered ketoreductase of SEQ ID NO: 2 shows 10% of the residual activity. The crude extract is then incubated on ice for 30 minutes. The insoluble proteins are separated by centrifugation and the remaining ketoreductase activity of the supernatant is analyzed in a standard ketoreductase assay. In this standard assay, a substrate suitable for ketoreductases, such as isopropanol, is oxidized by the ketoreductase to, for example, acetone, accompanied by the reduction of NAD + to NADH (since no other ketoreductase substrate is present in this standard assay, isopropanol is used as a substrate for the ketoreductase and is not used for cofactor regeneration). The increase of NADH is monitored by measuring the absorption at 340 nm in a standard photometer. The assay is performed under standard reaction conditions, typically at 30°C, in an aqueous buffer solution containing the substrate (e.g. isopropanol), the cofactor and the ketoreductase. The ketoreductase is preferably added as a crude extract supernatant. The crude extract is obtained by destroying the expression host containing the ketoreductase, followed by centrifugation to separate the cell debris and the ketoreductase containing crude extract supernatant. The buffer is preferably selected from 10-200 mM Tris / HCI, pH 7-9, containing 2 mM MgCI2, 10-200 mM sodium phosphate / NaOH, pH 6-8, or 10-200 mM triethanolamine / HCI, pH 7-9. The cofactor NAD + is preferably added to a final concentration ranging from 0.05-10 mM. The ketoreductase is preferably added as a crude extract supernatant. The crude extract is obtained by destroying the expression host containing the ketoreductase, followed by centrifugation to separate the cell debris and the ketoreductase containing crude extract supernatant.
[0143] In a preferred embodiment, the engineered ketoreductase of the present application differs from the wild type ketoreductase of SEQ ID NO: 2 by 1-70 amino acids, typically 1-50 amino acids, more typically 1-30 amino acids, even more typically 1-20 amino acids, most typically 1-11 amino acids.
[0144] In this respect, engineering means that one or more amino acids of a given position are substituted by any other proteinogenic amino acid selected from the group consisting of Ala, Arg, Asn, Asp, Cys, Gin, Glu, Gly, His, lie, Leu, Lys, Met, Phe, Pro, Ser, Thr, Trp Tyr and Val. In a preferred embodiment, the substitution does not change the sequence length, i.e. a single amino acid residue is replaced by another single amino acid residue. However, it is also possible that one or more amino acid residues are not replaced but deleted and / or one or more amino acid residues are inserted.
[0145] In principle, a substitution at any position of the enzyme can be a conservative substitution, where such amino acid is replaced by an amino acid of comparable character (e.g. a hydrophobic amino acid is replaced by another hydrophobic amino acid).

William Studier, Protein Expression and Purification 41 (2005) 207-234) supplemented with kanamycin (50 mg / 1) and chloramphenicol (34 mg / 1). Expression of the genes of the genomic library was induced by IPTG (0.1 mM) or arabinose (0.1 (v / v)) in the logarithmic phase. Cultivation was performed at 30°C for 16 hours.

In addition, the gene was optimized for E. coli expression with codons, while reducing the GC content (see SEQ ID NO: 2). The gene was cloned into the expression vector pLE1A27 (derivative of pRSF-1b, Novagen). The resulting plasmid was used to transform E. coli BL21 (DE3) cells.
[0245] For expression of the new ketoreductase gene corresponding to SEQ ID NO: 1, the cells were cultivated at 37°C in ZYM505 medium (F. William Studier, Protein Expression and Purification 41 (2005) 207-234) supplemented with kanamycin (50 mg / 1). The expression of the gene was induced by IPTG (0.1 mM) in the logarithmic phase and carried out at 30°C for 16-18 hours.
[0246] The cells were harvested by centrifugation (3220 x g, 20 min, 4°C) and the cells were disrupted with cell lysis buffer (50 mM Tris-HCl pH 7.0; 2 mM MgCl2, 1 x CelLytic B (Sigma); DNA nuclease 0.02 U, lysozyme 0.5 mg / ml). The crude extract was separated from the cell debris by centrifugation (3220 x g 30 min, 4°C).
[0247] The ketoreductase expression level of the crude extract was investigated by SDS-PAGE denaturation and its ability to reduce ethyl-4-chloro-3-oxo-butanoate by measuring the absorbance decrease at 340 nm caused by the oxidation of NAD(P)H.
[0248] Example 3:
[0249] Reduction of ethyl-4-chloro-3-oxo-butanoate to (3S)-4-chloro-3-hydroxy- butanoate by the new ketoreductase of SEQ ID NO: 2 on a preparative scale
[0250] In a 250 ml round bottom flask, equipped with a magnetic stirrer, 24.08 g D(+)-glucose monohydrate was dissolved in 0.1 M sodium phosphate buffer pH 6.5 to a final volume of 45 ml. The pH of the solution was adjusted to pH 6.5-6.6 with NaOH. 10.7 mg of the new ketoreductase of SEQ ID NO: 2, 22.9 mg of glucose dehydrogenase (GDH-03, commercially available at c-LEcta GmbH) and 39.8 mg of NAD + The flask was connected to a pH Stat titration device and adjusted to 35°C under stirring. The reaction was started by stepwise controlled addition of 18.18 g ethyl-4-chloro-3-oxo-butanoate in 9.375 ml n-butyl acetate. During the whole reaction time the mixture was stirred and adjusted to 35°C. The pH was automatically controlled by the pH-stat device by addition of NaOH (set point: pH = 6.5). The progress of the reaction was controlled by tracking the amount of 5 M NaOH automatically titrated by the pH Stat. After 22 hours the reaction was complete with a total conversion of > 99.9% analyzed by GC analysis. The reduced product showed an enantiomeric excess of > 99 for ethyl (3S)-4-chloro-3-hydroxy-butanoate.

[0252] Evaluation of the thermal stability of ketoreductase variants
[0253] The thermal stability of several ketoreductase variants that have been generated was analyzed. Melting curves were recorded by incubating the crude extract containing the ketoreductase at different temperatures for 15 minutes in a PCR cycler. The crude extract was then incubated on ice for 30 minutes. Insoluble proteins were separated by centrifugation and the remaining ketoreductase activity of the supernatant was analyzed in a standard ketoreductase assay. In this standard assay, isopropanol is oxidized by the ketoreductase to acetone, accompanied by the reduction of NAD + to NADH. The increase of the ketoreductase was monitored by measuring the absorbance at 340 nm in a standard photometer.
[0254] It was found that the ketoreductase corresponding to SEQ ID NO: 4 exhibited a melting temperature (Tm) that was 15°C higher than the Tm of the wild type ketoreductase of SEQ ID NO: 2.
