Enzyme reactions

• Enzyme class 1: E.C.3.4.21.98 - hepacivirin.
• Reaction: 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'.
• Enzyme class 2: E.C.3.6.1.15 - nucleoside-triphosphate phosphatase.
• Reaction: a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-diphosphate + phosphate + H⁺
• Enzyme class 3: E.C.3.6.4.13 - Rna helicase.
• Reaction: ATP + H2O = ADP + phosphate + H⁺

Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.
