Comments

Comment Type Description
Biophysicochemical Properties Kinetic parameters: KM=2.8 uM for calcidiol ; pH dependence: Optimum pH is 7.7. ;
Catalytic Activity Calcidiol + NADPH + O(2) = secalciferol + NADP(+) + H(2)O
Catalytic Activity Calcitriol + NADPH + O(2) = calcitetrol + NADP(+) + H(2)O
Cofactor Name=heme; Xref=ChEBI:CHEBI:30413; Evidence= ;
Function Has a role in maintaining calcium homeostasis. Catalyzes the NADPH-dependent 24-hydroxylation of calcidiol (25- hydroxyvitamin D(3)) and calcitriol (1-alpha,25-dihydroxyvitamin D(3)). The enzyme can perform up to 6 rounds of hydroxylation of calcitriol leading to calcitroic acid.
Similarity Belongs to the cytochrome P450 family
Subcellular Location Mitochondrion.
