M7G(5')pppN diphosphatase

In enzymology, a m7G(5')pppN diphosphatase is an enzyme that catalyzes the chemical reaction


 * 7-methylguanosine 5'-triphospho-5'-polynucleotide + H2O $$\rightleftharpoons$$ 7-methylguanosine 5'-phosphate + polynucleotide

Thus, the two substrates of this enzyme are 7-methylguanosine 5'-triphospho-5'-polynucleotide and H2O, whereas its two products are 7-methylguanosine 5'-phosphate and polynucleotide.

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is 7-methylguanosine-5'-triphospho-5'-polynucleotide 7-methylguanosine-5'-phosphohydrolase. Other names in common use include decapase, and m7G(5')pppN pyrophosphatase.
