“…14 • 15 ) These yglutamylpeptides were reported to be formed by the transpeptidation or the reversal of hydrolysis catalyzed by y-glutamyltranspeptidase. 16 ) Recently, it is reported that trans amidase from Bacillus natto catalyzed yglutamylpeptides formation. 17 ) In this study, various y-glutamylpeptides were synthesized by purified y-glutamylcysteine synthetase from P. mirabilis and the isolated peptides were identified by physicochemical analyses.…”
