  • Gene involved in synthesis of cyclic peptide compound, method for producing cyclic peptide compound using the same, and transformant comprising the same
    Patent number: 11946086
    Abstract: This invention is intended to identify a gene cluster involved in biosynthesis of a cyclic peptide compound produced by a filamentous fungus of the Curvularia species and to establish a system for synthesizing such cyclic peptide compound. The gene is composed of a first module to a tenth module and encodes a protein having activity of synthesizing a nonribosomal peptide constituting a basic peptide backbone of a cyclic peptide compound produced by a filamentous fungus of the Curvularia species.

  • Method for producing dihydrotentoxin
    Patent number: 11919928
    Abstract: An object of the present invention is to identify an enzyme having activity of synthesizing dihydrotentoxin that is a tentoxin precursor and an enzyme having activity of synthesizing tentoxin using dihydrotentoxin as a substrate. The present invention concerns a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 16 and having activity of nonribosomal peptide synthesis of dihydrotentoxin and a tentoxin synthesis-related gene encoding a protein comprising the amino acid sequence of SEQ ID NO: 18 and having activity of converting dihydrotentoxin to tentoxin.
