Comments [?]

Function mRNA decapping enzyme that specifically removes the nicotinamide adenine dinucleotide (NAD) cap from a subset of mRNAs by hydrolyzing the diphosphate linkage to produce nicotinamide mononucleotide (NMN) and 5' monophosphate mRNA. The NAD-cap is present at the 5'-end of some mRNAs and stabilizes RNA against 5'-processing. Has preference for mRNAs with a 5'-end purine. Catalyzes the hydrolysis of a broad range of dinucleotide pyrophosphates.
Catalytic activity RHEA:60876: a 5'-end NAD(+)-phospho-ribonucleoside in mRNA + H2O = a 5'-end phospho-adenosine-phospho-ribonucleoside in mRNA + beta-nicotinamide D-ribonucleotide + 2 H(+)
PhysiologicalDirection=left-to-right (RHEA:60877)
RHEA:11800: H2O + NAD(+) = AMP + beta-nicotinamide D-ribonucleotide + 2 H(+)
EC 3.6.1.22
RHEA:48868: H2O + NADH = AMP + 2 H(+) + reduced beta-nicotinamide D-ribonucleotide
EC 3.6.1.22
