|Endopeptidase with a preference for cleavage when the P1 position is occupied by Glu-|-Xaa and the P1' position is occupied by Gly-|-Yaa|
- Viruses that are members of the Norovirus genus (Caliciviridae
family) are a major cause of epidemic acute viral gastroenteritis.
- The nonstructural proteins of these viruses are produced by
proteolytic cleavage of a large precursor polyprotein, performed by a
protease that is incorporated into the polyprotein.
- Cleavage sites are apparently defined by features based on both
sequence and structure since several sites in the polyprotein
fulfilling the identified sequence requirements are not cleaved.
- The presence of acidic (Asp), basic (Arg), aromatic (Tyr) or
aliphatic (Leu) amino acids at the P1' position results in only minor
differences in cleavage efficiency, suggesting that steric or
conformational constraints may play a role in determining
- Changes to the amino acid at the P2 position do not alter cleavage
- Belongs to peptidase family C37.
