Enzyme Information
| 1.14.14.24 | Vitamin D 25-hydroxylase. based on mapping to UniProt Q6VVX0 Calciol + O(2) + [reduced NADPH--hemoprotein reductase] = calcidiol + [oxidized NADPH--hemoprotein reductase] + H(2)O. -!- A microsomal enzyme isolated from human and mouse liver that bioactivates vitamin D(3). -!- While multiple isoforms (CYP27A1, CYP2J2/3, CYP3A4, CYP2D25 and CYP2C11) are able to catalyze the reaction in vitro, only CYP2R1 is thought to catalyze the reaction in humans in vivo. -!- The direct electron donor to the enzyme is EC 1.6.2.4. -!- Formerly EC 1.14.13.159. |
