Other name(s): FAD pyrophosphatase; riboflavin adenine dinucleotide pyrophosphatase; flavin adenine dinucleotide pyrophosphatase; riboflavine adenine dinucleotide pyrophosphatase; flavine adenine dinucleotide pyrophosphatase
Systematic name: FAD nucleotidohydrolase
Comments: The plant enzyme also hydrolyses NAD+ and NADH; the animal enzyme hydrolyses NAD+ and CoA at about half of the rate of hydrolysis of FAD. May be identical with EC 18.104.22.168 nucleotide diphosphatase.
