  • mtgA GENE-DEFICIENT MICROORGANISM
    Publication number: 20180163236
    Abstract: Provided is a bacterial strain having a mutation in the gene that codes for monofunctional peptidoglycan transglycosylase (MtgA), wherein the mutation inactivates MtgA or reduces the activity of MtgA in comparison to a control strain lacking the mutation.
    Type: Application
    Filed: May 26, 2016
    Publication date: June 14, 2018
    Applicant: NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY
    Inventors: Seiichi TAGUCHI, Ryosuke KADOYA
  • mutant strain
    Patent number: 7981659
    Abstract: Novel Bacillus subtilis mutant strains having good productivity of various enzymes are provided through extensive analysis of strains that are derived from Bacillus subtilis via gene disruption. The Bacillus subtilis mutant strains according to the present invention have genomic structures prepared by deletion of regions listed in the columns for deficient regions. Each of these Bacillus subtilis mutant strains exerts significantly improved secretory productivity of a protein when a gene encoding such a secretory target protein is introduced so that it can be expressed, compared with a case in which the same gene is introduced into a wild-type strain.
    Type: Grant
    Filed: September 25, 2006
    Date of Patent: July 19, 2011
    Assignees: Kao Corporation, Nara Institute of Science and Technology
    Inventors: Ryosuke Kadoya, Keiji Endo, Masatoshi Tohata, Katsutoshi Ara, Naotake Ogasawara
