A process for producing a polyester, which is obtained by the homopolymerization or copolymerization of a 3-hydroxyalkanoic acid and has biodegradability and excellent properties, using a yeast as a host. One or more enzyme genes participating in the synthesis of a polyester, each having DNA encoding peroxisome-targeting signal added thereto, are constructed and an enzyme gene expression cassette is transferred into a yeast. The thus obtained transformant is cultured so as to accumulate a polyester obtained by the homopolymerization or copolymerization of a 3-hydroxyalkanoic acid in the cells. Then, the polymer can be collected from the culture. |
