Zingibain
Zingibain, zingipain, or ginger protease is a cysteine protease enzyme found in ginger ( Zingiber officinale) rhizomes. It catalyses the preferential cleavage of peptides with a proline residue at the P2 position. It has two distinct forms, ginger protease I (GP-I) and '''ginger protease II '''(GP-II).
