Rhizopuspepsin-3

Gene
N/A
Organism
Rhizopus niveus
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Catalytic activityi

Hydrolysis of proteins with broad specificity similar to that of pepsin A, preferring hydrophobic residues at P1 and P1'. Clots milk and activates trypsinogen. Does not cleave 4-Gln-|-His-5, but does cleave 10-His-|-Leu-11 and 12-Val-|-Glu-13 in B chain of insulin.
