EC 3.6.1.53     
Accepted name: Mn2+-dependent ADP-ribose/CDP-alcohol diphosphatase
Reaction: (1) CDP-choline + H2O = CMP + phosphocholine
(2) ADP-D-ribose + H2O = AMP + D-ribose 5-phosphate
Other name(s): Mn2+-dependent ADP-ribose/CDP-alcohol pyrophosphatase; ADPRibase-Mn
Systematic name: CDP-choline phosphohydrolase
Comments: Requires Mn2+. Unlike EC 3.6.1.13, ADP-ribose diphosphatase, it cannot utilize Mg2+. ADP-D-ribose, CDP-choline, CDP-ethanolamine and ADP are substrates for this enzyme but ADP-D-glucose, UDP-D-glucose, CDP-D-glucose, CDP, CMP and AMP are not hydrolysed [2]. In rat, the enzyme is found predominantly in thymus and spleen.
