M7GpppX diphosphatase (original) (raw)

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 7-methylguanosine 5'-phosphate + pp5'N(3'ppp5'N)n(2) 7-methylguanosine 5'-diphosphate + H2O 7-methylguanosine 5'-phosphate + phosphate Decapping is a process in the control of eukaryotic mRNA degradation.
