883 results about "Tert-leucine" patented technology

The leucines are primarily the four isomeric amino acids: leucine, isoleucine, tert-leucine and norleucine. Being compared with the four butanols, they could be classified as butyl-substituted glycines; they represent all four possible variations. Leucine and isoleucine belong to the proteinogenic amino acids; the others are non-natural.

Engineered transgene integration platform (ETIP) for gene targeting and trait stacking

An Engineered Transgene Integration Platform (ETIP) is described that can be inserted randomly or at targeted locations in plant genomes to facilitate rapid selection and detection of a GOI that is perfectly targeted (both the 5′ and 3′ ends) at the ETIP genomic location. One element in the subject disclosure is the introduction of specific double stranded breaks within the ETIP. In some embodiments, an ETIP is described using zinc finger nuclease binding sites, but may utilize other targeting technologies such as meganucleases, CRISPRs, TALs, or leucine zippers. Also described are compositions of, and methods for producing, transgenic plants wherein the donor or payload DNA expresses one or more products of an exogenous nucleic acid sequence (e.g. protein or RNA) that has been stably-integrated into an ETIP in a plant cell. In embodiments, the ETIP facilitates testing of gene candidates and plant expression vectors from ideation through Development phases.

Gene products of bacillus licheniformis which form odorous substances and improved biotechnological production methods based thereon

The present invention relates to 25 hitherto undescribed genes of B. licheniformis and gene products derived therefrom and all sufficiently homologous nucleic acids and proteins thereof. They occur in five different metabolic pathways for the formation of odorous substances. The metabolic pathways in question are for the synthesis of: 1) isovalerian acid (as part of the catabolism of leucine), 2) 2-methylbutyric acid and / or isobutyric acid (as part of the catabolism of valine and / or isoleucine), 3) butanol and / or butyric acid (as part of the metabolism of butyric acid), 4) propyl acid (as part of the metabolism of propionate) and / or 5) cadaverine and / or putrescine (as parts of the catabolism of lysine and / or arginine). The identification of these genes allows biotechnological production methods to be developed that are improved to the extent that, to assist these nucleic acids, the formation of the odorous substances synthesized via these metabolic pathways can be reduced by deactivating the corresponding genes in the micro-organism used for the biotechnological production. In addition, these gene products are thus available for preparing reactions or for methods according to their respective biochemical properties.

Magnesium (II) represents the preferred metal ion as magnesium is known to have neuroprotective effects. The metal ion is in part chelated by a non-steroidal anti-inflammatory drug that does not inhibit platelet activity and includes salicylate and ibuprofenate. The complex also includes a ligand operative in transport across the blood brain barrier. A process for making an inventive complex includes the stoichiometric addition of ligands containing carboxylate groups to a solution of the metal ion. In instances where the metal ion is magnesium (II), a stoichiometric ratio of 1:1:1 is found between the non-steroidal anti-inflammatory ligand:magnesium (II):transporter ligand.

Surfactant peptide nanostructures, and uses thereof

This work describes a new class of short polypeptides that can self-assemble to form regular nanotubes with an average diameters of about 50 nm. These peptides (7 to 8 amino acids) have a structure very similar to those observed in surfactant molecules with a defined hydrophilic head group constituting of charged amino acids and a lipophilic tail made out of hydrophobic amino acids such as alanine, valine or leucine. Cryo-TEM micrographs show numerous three-fold junctions connecting the self-assembling nanostructures and thus leading to the formation of a rather dense network of entangled nanotubes. Additionally, the observation of clear openings at the end of the supramolecular structures confirms the presence of tubular organization.
