Patent ID: 7858348

Claim:
A method for manufacturing β-amino acids comprising: a) contacting a microorganism which has been transformed with a gene with an N-acetyl-β-amino acid, b) inducing the production of the β-amino acid, and c) recovering the β-amino acid; wherein said gene comprises a DNA selected from the group consisting of: (A) DNA comprising the nucleotide sequence shown in SEQ ID NO: 7; (B) DNA encoding a protein having N-acetyl-(R)-β-amino acid acylase activity, wherein said DNA is able to hybridize under stringent conditions with a DNA which is complementary to the nucleotide sequence shown in SEQ ID NO: 7; and (C) DNA encoding a protein having N-acetyl-(R)-β-amino acid acylase activity, wherein the DNA has 95% or greater sequence homology with the nucleotide sequence shown in SEQ ID NO: 7; and wherein said stringent conditions comprise washing at 60° C. with 1×SSC, and 0.1 percent SDS.
