ENZYME entry: EC 3.4.21.115

Accepted Name
Infectious pancreatic necrosis birnavirus Vp4 peptidase.
Alternative Name(s)
Infectious pancreatic necrosis virus protease.
IPNV Vp4 peptidase.
IPNV Vp4 protease.
NS protease.
NS-associated protease.
Vp4 protease.
Reaction catalysed
Cleaves the (Ser/Thr)-Xaa-Ala-\|-(Ser/Ala)-Gly motif in the polyprotein NH(2)-pVP2-VP4-VP3-COOH of infectious pancreatic necrosis virus at the pVP2-VP4 and VP4-VP3 junctions
Comment(s)
Infectious pancreatic necrosis virus (IPNV) is a birnavirus that causes an acute, contagious disease in young salmonid fish. As with most viruses that infect eukaryotic cells, the proteolytic processing of viral precursor proteins is a crucial step in the life cycle of this virus. pVP2 is converted into VP2 by cleavage near the carboxy end of pVP2; this cleavage is most likely due to host-cell proteases rather than VP4. Differs from most serine peptidases in not having the catalytic triad Ser-His-Asp. Belongs to peptidase family S50.
