Among the fewer than 10 proteins primarily secreted by the species Lactobacillus plantarum, there is one of 30 kDa that contains an internal fragment without cleavage sites for the most important intestinal proteases and characterized by having a serine and threonine content of at least 50%. The genetic information encoded in this fragment, designated ST peptide, has been used for producing and purifying said peptide, thus making it possible to conduct various tests in vitro.

To summarize, the ST peptide is considered to promote the process of immunologic ignorance of our gastrointestinal immune system toward the commensal bacteria of our gastrointestinal tract, thus favoring the mechanisms of oral tolerance. Therefore the ST peptide could be used in immunotherapy, especially in the context of certain autoimmune diseases and certain inflammatory diseases.

It is intended to provide a process for producing a highly safe seasoning by highly decomposing meat or a bone residue remaining after taking meat (in particular, chicken meat, chicken bone or culled chicken) with enzymes. It is also intended to utilize nitrogen at an elevated ratio compared with the existing low nitrogen utilization level. In decomposing protein in chicken meat, culled chicken or chicken bone, muscular protein alone is decomposed by using an autolyzing enzyme or an autolyzing enzyme with an enzymatic agent containing peptidase. In the case of using chicken meat as the raw material, it contains trace constituents of meat (taurin, anserine, carnosine, creatine, etc.) and the content of Hyp (oxyproline) is controlled to 0.5% by mass or less to the protein. In the case of using culled chicken or chicken bone as the raw material, it contains trace constituents of meat (taurin, anserine, carnosine, creatine, etc.) and the content of Hyp (oxyproline) is controlled to 1.0% by mass or less to the protein.

The invention provides feruloyl esterase and a preparing method and application thereof. A feruloyl esterase gene coming from a soil macro gene library have the nucleotide sequence and amino acid sequence shown in SEQ ID NO.1 and SEQ ID NO.2. The gene contains a tetrapeptide SXXK sequence motif which is rarely seen, and after the esterase gene is inserted into plasmid pET28a(+), the gene is transformed into escherichia coli BL21(DE3) to achieve heterogeneous expression. The molecular weight of purified recombinase (DLFae4) is 38.3 kDa. Besides, it is put forward for the first time that novel feruloyl esterase can hydrolyze penbritin, penicillin, cefazolin and other lactam antibiotics. As is shown by site-directed mutagenesis experiments, a catalysis triplet of DLFae4 is composed of serine(S11), histidine (H74) and aspartic acid (D302), and the mutation of any of serine (S11), histidine (H74) and aspartic acid (D302) can cause loss of the catalysis capability of DLFae4. DLFae4 has a high hydrolytic activity on methyl ferulate and has good heat stability. In the presence of cellulase, DLFae4 can obviously increase the amount of ferulic acid released from destarched wheat bran. Due to peculiar activities and enzymatic characteristics of novel feruloyl esterase, novel feruloyl esterase can be applied to feed, paper making, food, pharmacy and other fields.
