NOVEL TRANSAMINASE SHOWING HIGH ACTIVITY FOR GLUTAMIC ACID GENE ENCODING SAME AND METHOD FOR UTILIZATION THEREOF

摘要

Provided is a method for economically and efficiently producing an optically active amino compound which is useful as an intermediate for drugs pesticides and so on from a ketone compound. A novel polypeptide having a transaminase activity said polypeptide showing a higher activity for glutamic acid than for L alanine as an amino donor and forming (S)1 benzyl 3 pyrrolidinone at a high optical purity of 93% or greater a gene encoding the polypeptide and a transformant highly expressing the gene.
