  • Mutant poly(3-hydroxyalkanoic acid) synthases
    Patent number: 7456002
    Abstract: Biodegradable polyester with desired physical properties. A mutant poly(3-hydroxyalkanoic acid) synthase comprising an amino acid sequence of (a) or (b) below. (a) A mutant amino acid sequence derived from SEQ ID No. 1, wherein at least one amino acid selected from the group consisting of glutamic acid at position 130, serine at position 325, serine at position 477 and glutamine at position 481 is substituted by another amino acid. (b) A mutant amino acid sequence derived from SEQ ID No. 1 wherein at least one amino acid selected from the group consisting of glutamic acid at position 130, serine at position 325, serine at position 477 and glutamine at position 481 is substituted by another amino acid, wherein at least one amino acid other than the amino acids at positions 130, 325, 477 and 481 is deleted, substituted and/or added, wherein the mutant amino acid sequence has the activity to biosynthesize biodegradable polyester.
