ENTRY       EC 3.6.1.18
NAME        FAD pyrophosphatase
CLASS       Hydrolases
            Acting on acid anhydrides
            In phosphorus-containing anhydrides
SYSNAME     FAD nucleotidohydrolase
REACTION    FAD + H2O = AMP + FMN
SUBSTRATE   FAD
            H2O
PRODUCT     AMP
            FMN
COMMENT     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 3.6.1.9.
