  • MUTANT POLYHYDROXYALKANOATE SYNTHETASE, GENE THEREOF AND TRANSFORMANT, AND METHOD FOR PRODUCING POLYHYDROXYALKANOATE
    Publication number: 20200354696
    Abstract: A mutant PHA synthetase which enables production of a PHA copolymer with a high or low 3HH ratio while maintaining PHA productivity. The mutant PHA synthetase is a mutant polyhydroxyalkanoate synthetase having an amino acid sequence having 85% or more sequence identity with the amino acid sequence of SEQ ID NO: 1 and having at least one of the following mutations (a) to (c): (a): mutation of substitution of serine at 389th position from N-terminus of the amino acid sequence of SEQ ID NO: 1 with an amino acid other than serine; (b): mutation of substitution of leucine at 436th position from the N-terminus of the amino acid sequence of SEQ ID NO: 1 with an amino acid other than leucine; and (c): mutation of deletion of 11 or more and 19 or less amino acid residues from C-terminus of the amino acid sequence of SEQ ID NO: 1.
