MUTANT Y-GLUTAMYLTRANSFERASE, AND METHOD FOR PRODUCING Y-GLUTAMYLVALYLGLYCINE OR SALT THEREOF

摘要

A method for producing ³-Glu-Val-Gly comprising the step of reacting Val-Gly with a ³-glutamyl group donor in the presence of a ³-glutamyltransferase, a microorganism containing the enzyme, or a processed product thereof to generate ³-Glu-Val-Gly, wherein the ³-glutamyltransferase consists of a large subunit and a small subunit, and the small subunit has a specific mutation.
