Comments
[?]
| Function | Catalyzes specifically the NADPH-dependent reduction of coenzyme A disulfide. |
| Catalytic activity | RHEA:14705: 2 CoA + NADP(+) = CoA-disulfide + H(+) + NADPH
EC 1.8.1.14 |
| Cofactor | FAD Note: Binds 1 FAD per subunit. |
| Subunit | Homodimer. |
| Domain | Contains 2 FAD binding domains and a single NADPH binding domain. |
| Miscellaneous | Reduction of disulfides occurs by a thiol-disulfide exchange reaction, but involves only a single catalytic cysteine residue that forms a stable mixed disulfide with CoA during catalysis. |
| Similarity | Belongs to the class-III pyridine nucleotide-disulfide oxidoreductase family. |
