  • L-succinylaminoacylase and process for producing L-amino acid using it
    Patent number: 8470574
    Abstract: The present invention provides an L-aminoacylase which is able to produce L-tert-leucine being useful as an intermediate for pharmaceuticals. A protein which is characterized in being represented by any of the following (a) to (d): (a) a protein coded by a gene consisting of a nucleic acid sequence shown in SEQ ID No: 1; (b) a protein consisting of an amino acid sequence shown in SEQ ID No: 2; (c) a protein coded by a polynucleotide which hybridizes under a stringent condition with a nucleic acid sequence which is complementary to the nucleic acid sequence shown in SEQ ID No: 1 and having an L-succinylaminoacylase activity; and (d) a protein which consists of an amino acid sequence where one or several amino acid (s) is/are substituted, deleted, inserted and/or added in the protein consisting of the amino acid sequence shown in SEQ ID No: 2 and has an L-succinylaminoacylase activity.
