Function and Biology Details

Reactions catalysed:
ATP + H(2)O = ADP + phosphate
ATP + RNA(n) = diphosphate + RNA(n+1)
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
ADP-D-ribose 1''-phosphate + H(2)O = ADP-D-ribose + phosphate
NTP + H(2)O = NDP + phosphate
A 5'-triphospho-[mRNA] + H(2)O = a 5'-diphospho-[mRNA] + phosphate
