Patent ID: 7943351

Claim:
In a production process of a macromolecular compound using an acyltransferase reaction, in which an acyl group of acyl coenzyme A (acyl CoA) is transferred, wherein the reaction is carried out by production and/Pr reproduction of acyl coenzyme A from coenzyme A in a reaction system by a chemical thioester exchange reaction with an acyl group donor which is an acyl ester of a thiol compound; wherein an acyl group donor, acyl group receptor, coenzyme A and acyltransferase are contained in the reaction system at the same time, an acyl group of the acyl group donor is transferred to coenzyme A by a chemical thioester exchange reaction to give an acyl coenzyme A and an acyl group of the acyl coenzyme A is transferred to the acyl group receptor; wherein the acyltransferase is a macromolecular polymerization enzyme and a macromolecular compound is synthesized in a reaction in which an acyl group donor, acyl group receptor, coenzyme A and acyltransferase are contained in the reaction system at the same time, an acyl group of the acyl group donor is transferred to coenzyme A by a chemical thioester exchange reaction to give an acyl coenzyme A and an acyl group of the acyl coenzyme A is transferred to the acyl group receptor; and a production process of polyester in which the macromolecular compound is polyester.
