Research Abstract

Highly homogenious polyester can be synthesized by genetic-information-based synthesis of polypeptide-like polymers. In this study, an aminoacyl-tRNA synthetase was altered for the incorporation of ester bond into the polymers synthesized on ribosome. As a result, the mutant enzymes, which efficiently recognize the building block of the ester bonds, were found. By using these enzymes, the in vitro translation system that synthesizes polymers containing two serially polymerized α-hydroxyacids, was successfully established.
