M7GpppX diphosphatase (EC 3.6.1.59, DcpS, m7GpppX pyrophosphatase, m7GpppN m7GMP phosphohydrolase) is an enzyme with systematic name m7G5'ppp5'N m7GMP phosphohydrolase. This enzyme catalyses the following chemical reaction
(1) m7G5'ppp5'N(3'ppp5'N)n + H2O
⇌
{\displaystyle \rightleftharpoons }
7-methylguanosine 5'-phosphate + pp5'N(3'ppp5'N)n
(2) 7-methylguanosine 5'-diphosphate + H2O
⇌
{\displaystyle \rightleftharpoons }
7-methylguanosine 5'-phosphate + phosphate
Decapping is a process in the control of eukaryotic mRNA degradation.
