Abstract:
1. An isolated microorganism which originally has a polyhydroxyalkanoic acid synthase gene in chromosome, in which at least a part of said polyhydroxyalkanoic acid synthase gene is substituted with an exogenous polyhydroxyalkanoic acid synthase gene to lose enzymatic activity of polypeptide encoded by said polyhydroxyalkanoic acid synthase gene originally in chromosome for expression of a single protein encoded by the exogenous polyhydroxyalkanoic acid synthase gene or a fusion protein with a protein encoded by the gene before substitution, and produces a copolyester constituted of two or more monomer units selected from the group consisting of: 3-hydroxybutyric acid, 3-hydroxyhexanoic acid, 3-hydroxyheptanoic acid, 3-hydroxyoctanoic acid, 3-hydroxynonanoic acid, 3-hydroxydecanoic acid, 3-hydroxyundecanoic acid, 3-hydroxydodecanoic acid, 3-hydroxytridecanoic acid, 3-hydroxytetradecanoic acid, 3-hydroxypentadecanoic acid, and 3-hydroxyhexadecanoic acid.
