Enzyme Commission Primary Name: glutamyl endopeptidase II
Enzyme Commission Synonyms: GluSGP
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): 36.144756 [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
