Accepted name: glutamyl endopeptidase II

Reaction: Preferential cleavage: -Glu >> -Asp . Preference for Pro or Leu at P2 and Phe at P3. Cleavage of -GluAsp- and -GluPro- bonds is slow

Other names: GluSGP

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