Protein: 4'-phosphopantetheine phosphatase (Q9NVE7)
Organism: Homo sapiens (Human)
Function: Phosphatase which shows a preference for 4'- phosphopantetheine and its oxidatively damaged forms (sulfonate or S- sulfonate), providing strong indirect evidence that the phosphatase activity pre-empts damage in the coenzyme A (CoA) pathway . Hydrolyzing excess 4'-phosphopantetheine could constitute a directed overflow mechanism to prevent its oxidation to the S-sulfonate, sulfonate, or other forms. Hydrolyzing 4'-phosphopantetheine sulfonate or S-sulfonate would forestall their conversion to inactive forms of CoA and acyl carrier protein. May play a role in the physiological regulation of CoA intracellular levels (Probable)
