  • glutathione + H2O --> L-cysteinylglycine + L-glutamate (according to UniProt)
  • S-substituted glutathione + H2O --> S-substitued L-cysteinylglycine + L-glutamate (according to UniProt)

    • Protein family

  • gamma-glutamyltransferase family (with [protein|F1DF59528E340A65A982BD7E6621DDA82C10B2B5|YwrD], according to UniProt)

    regulation

  • strongly induced in response to glucose starvation in M9 medium [Pubmed|23033921]

    • additional information

  • [protein|search|translation] is likely to require [protein|search|Efp] due to the presence of several consecutive proline residues [PubMed|23239624,23239623]
