Reaction: coenzyme A + H2O = adenosine 3',5'-bisphosphate + 4'-phosphopantetheine
Other name(s): CoA pyrophosphatase; coenzyme A pyrophosphatase; CoA diphosphohydrolase; Nudt19; Nudt7; thnR (gene name)
Systematic name: coenzyme A 4'-phosphopantetheine phosphohydrolase
Comments: The enzyme belongs to the Nudix hydrolase family. It has been reported from bacteria, yeast, and mammals. Activity is higher with oxidized disulfide CoA than with reduced CoA.
