Mass balance status: The left side is missing: Peptides: 2 . The right side is missing: Proteins: 1 O: 1 H: 1

Enzyme Commission Primary Name: glutamyl endopeptidase II

Enzyme Commission Synonyms: GluSGP

Taxonomic Range: Bacteria

Standard Gibbs Free Energy (ΔrG in kcal/mol): 36.144756 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
This enzyme catalyzes preferential cleavage: -Glu-|- >> -Asp-|- . Preference for Pro or Leu at P2 and Phe at P3. Cleavage of -Glu-|-Asp- and -Glu-|-Pro- bonds is slow.

From Streptomyces griseus. A peptidase of family S1 (trypsin family). Inhibited by [Leu18→Glu]-modified turkey ovomucoid third domain
