 Enzyme reactions 
   Enzyme class 2: E.C.2.7.7.48  - RNA-directed Rna polymerase.
[IntEnz]   [ExPASy]   [KEGG]   [BRENDA]
      Reaction: RNA(n) + a ribonucleoside 5'-triphosphate = RNA(n+1) + diphosphate
RNA(n)
+ ribonucleoside 5'-triphosphate
= RNA(n+1)
+ diphosphate
   Enzyme class 3: E.C.3.4.22.28  - picornain 3C.
[IntEnz]   [ExPASy]   [KEGG]   [BRENDA]
      Reaction: Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly.
   Enzyme class 4: E.C.3.4.22.29  - picornain 2A.
[IntEnz]   [ExPASy]   [KEGG]   [BRENDA]
      Reaction: Selective cleavage of Tyr-|-Gly bond in the picornavirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly.
   Enzyme class 5: E.C.3.6.1.15  - nucleoside-triphosphate phosphatase.
[IntEnz]   [ExPASy]   [KEGG]   [BRENDA]
      Reaction: a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-diphosphate + phosphate + H+
ribonucleoside 5'-triphosphate
+ H2O
= ribonucleoside 5'-diphosphate
+ 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.
