M7G(5')pppN diphosphatase

In enzymology, a m7G(5')pppN diphosphatase or m7G(5')pppN pyrophosphatase (EC 3.6.1.59) is an enzyme that catalyzes the chemical reaction 7-methylguanosine 5'-triphospho-5'-polyribonucleotide + H2O ⇌ {\displaystyle \rightleftharpoons } 7-methylguanosine 5'-phosphate + 5'-diphospho-polyribonucleotide 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 5'-diphospho-polyribonucleotide. This is the enzyme involved in the processing of amphetamines of the cathinone group, including mephedrone and khat.
