Glycyl endopeptidase (EC 3.4.22.25, papaya peptidase B, papaya proteinase IV, glycine-specific proteinase, chymopapain, Papaya proteinase 4, PPIV, chymopapain M) is an enzyme.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

Preferential cleavage: Gly-, in proteins and small molecule substrates

This enzyme is isolated from the papaya plant, Carica papaya.
