The protein

Catalyzed reaction/ biological activity

• (5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl amino acid (according to Swiss-Prot)

Structure

• [PDB|2V36]

[SW|Localization]

• extracellular (signal peptide) [Pubmed|18957862]

Expression and Regulation

Operons

• genes: [gene|5C31D968E3786858B025CE02CFAC48F61700031F|ggt]
  description: [Pubmed|22383849]

  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]
