Gene encoding new aminotransferase show high activity in glutamic acid, and the same, and of these usage

摘要

To provide a method for efficiently producing at a low cost from a ketone compound, useful optically active amino compound as an intermediate for pharmaceuticals and agricultural chemicals. And shows high activity in glutamate than L- alanine as the amino donor, a polypeptide that has a new aminotransferase activity to produce high optical purity of more than 93% (S) 1--benzyl-3-pyrrolidinone, gene encoding the same, transformants that express high levels of the gene.
