ENZYME: 1.14.15.16

Entry

EC 1.14.15.16               Enzyme

Name

vitamin D3 24-hydroxylase;
CYP24A1

Class

Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced iron-sulfur protein as one donor, and incorporation of one atom of oxygen into the other donor

Sysname

calcitriol,adrenodoxin:oxygen oxidoreductase (24-hydroxylating)

Reaction(IUBMB)

(1) calcitriol + 2 reduced adrenodoxin + 2 H+ + O2 = calcitetrol + 2 oxidized adrenodoxin + H2O [RN:R09515];
(2) calcidiol + 2 reduced adrenodoxin + 2 H+ + O2 = secalciferol + 2 oxidized adrenodoxin + H2O [RN:R09516]

Reaction(KEGG)

R09515 R09516

Substrate

calcitriol [CPD:C01673];
reduced adrenodoxin [CPD:C00662];
H+ [CPD:C00080];
O2 [CPD:C00007];
calcidiol [CPD:C01561]

Product

calcitetrol [CPD:C18231];
oxidized adrenodoxin [CPD:C00667];
H2O [CPD:C00001];
secalciferol [CPD:C07712]

Comment

This mitochondrial cytochrome P-450 enzyme requires adrenodoxin. The enzyme can perform up to 6 rounds of hydroxylation of the substrate calcitriol leading to calcitroic acid. The human enzyme also shows 23-hydroxylating activity leading to 1,25 dihydroxyvitamin D3-26,23-lactone as end product while the mouse and rat enzymes do not. The initial source of the electrons is NADPH, which transfers the electrons to the adrenodoxin via EC 1.18.1.6, adrenodoxin-NADP+ reductase.

History

EC 1.14.15.16 created 2011 as EC 1.14.13.126, transferred 2016 to EC 1.14.15.16
