Accepted name: V-cath endopeptidase

Reaction: Endopeptidase of broad specificity, hydrolyzing substrates of both cathepsin L and cathepsin B

Other name(s): AcNPV protease; BmNPV protease; NPV protease; baculovirus cathepsin; nucleopolyhedrosis virus protease; viral cathepsin

Comments: In peptidase family C1. Contributes to the liquefaction of the tissues of the insect host in the late stages of infection by the baculovirus.
