Coenzyme A (CoASH) is a necessary cofactor for the oxidation of lipids in peroxisomes. Peroxisomal coenzyme A diphosphatase (NUDT7) mediates the cleavage of CoA (and CoA esters and oxidised CoA) to produce 3',5'-ADP and 4'-phosphopantetheine (PPANT) and is suggested to be involved in the regulation of peroxisomal CoASH levels. Human NUDT7 activity is inferred from mouse Nudt7 activity (Gasmi et al. 2001, Reilly et al. 2008).
