Reaction(IUBMB)
Preferential cleavage of peptides with a proline residue at the P2 position
Comment
This enzyme is found in ginger (Zingiber officinale) rhizome and is a member of the papain family. GP-II contains two glycosylation sites. The enzyme is inhibited by some divalent metal ions, such as Hg2+, Cu2+, Cd2+ and Zn2+ [2]. Belongs in peptidase family C1.
