IntEnz Enzyme Nomenclature
EC 3.6.1.22

Names

Accepted name:
NAD+ diphosphatase
Other names:
NPY1 (gene name)
nudC (gene name)
NUDT7 (gene name)
nicotinamide adenine dinucleotide pyrophosphatase
NADP pyrophosphatase
NADH pyrophosphatase
NAD+ phosphohydrolase
Systematic name:
NAD(H) phosphohydrolase

Reactions

Comments:

This enzyme, described from plants, animals, and bacteria, can act on both reduced and oxidized forms of its substrate, although enzymes from different organisms have different preferences. Also acts on other dinucleotides, including NADP(H), FAD(H2), and the thionicotinamide analogues of NAD+ and NADP+.
