Additional information

The gene is annotated in KEGG as an ortholog of gamma-glutamyltranspeptidase EC 2.3.2.2, This enzyme is necessary to utilize glutathione (GSH) as the sulfur source. No EC annotation for this gene is available in Swiss-Prot/MetaCyc. It has been shown by Minami et al. (PubMed) that ywrD mutant grows well on minimal media supplied with GSH as the sole sulfur source. In addition, His-tag purified ywrD cannot hydrolyze GSH. PubMed
