Function and Biology Details

Reactions catalysed:
Polyphosphate + n H(2)O = (n+1) oligophosphate
Diphospho-myo-inositol polyphosphate + H(2)O = myo-inositol polyphosphate + phosphate
A 5'-(N(7)-methyl 5'-triphosphoguanosine)-[mRNA] + H(2)O = N(7)-methylguanosine 5'-phosphate + a 5'-diphospho-[mRNA]
P(1),P(4)-bis(5'-adenosyl)tetraphosphate + H(2)O = ATP + AMP
5'-(N(7)-methylguanosine 5'-triphospho)-[mRNA] + H(2)O = N(7)-methylguanosine 5'-diphosphate + 5'-phospho-[mRNA]
