CC -!- FUNCTION: mRNA decapping enzyme that specifically removes the
CC nicotinamide adenine dinucleotide (NAD) cap from a subset of mRNAs by
CC hydrolyzing the diphosphate linkage to produce nicotinamide
CC mononucleotide (NMN) and 5' monophosphate mRNA. The NAD-cap is present
CC at the 5'-end of some mRNAs and stabilizes RNA against 5'-processing.
CC Has preference for mRNAs with a 5'-end purine. Catalyzes the hydrolysis
CC of a broad range of dinucleotide pyrophosphates. {ECO:0000255|HAMAP-
CC Rule:MF_00297}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5'-end NAD(+)-phospho-ribonucleoside in mRNA + H2O = a 5'-
CC end phospho-adenosine-phospho-ribonucleoside in mRNA + beta-
CC nicotinamide D-ribonucleotide + 2 H(+); Xref=Rhea:RHEA:60876,
