| Comments | Encoded by the genome of the viruses of the hepatitis C group, and contributes to the maturation of the precursor polyproteins. The enzyme is greatly activated by binding of the 54-residue NS4A ‘cofactor’ protein also derived from the viral polyprotein. Type example of peptidase family?S29. The crystallographic structure shows a chymotrypsin-like fold. |
| Cofactor | |
| History | |
| Reactions | Hydrolysis of four peptide bonds in the viral precursor polyprotein, commonly with Asp or Glu in the P6 position, Cys or Thr in P1 and Ser or Ala in P1′. |
