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:0000256|HAMAP-
CC Rule:MF_00297}.
CC -!- CATALYTIC ACTIVITY:
