Enzyme reactions

• Enzyme class 1: Chain A: E.C.2.7.7.6 - DNA-directed Rna polymerase.
• Reaction: RNA(n) + a ribonucleoside 5'-triphosphate = RNA(n+1) + diphosphate
• Enzyme class 2: Chain B: E.C.?

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.
