The protein

Basic information/ Evolution

• Catalyzed reaction/ biological activity: (5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl amino acid (according to Swiss-Prot), however, all evidence suggests this is a misannotation PubMed

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
