The
enzyme catalyzes the
hydroxylation of
calcifediol to
calcitriol (the bioactive form of
Vitamin D): :calcidiol + 2 reduced
adrenodoxin + 2 H+ + O2 calcitriol + 2 oxidized adrenodoxin + H2O The enzyme is also able to oxidize ercalcidiol (25-OH D2) to ercalcitriol, secalciferol to calcitetrol, and 25-hydroxy-24-oxocalciol to (1S)-1,25-dihydroxy-24-oxocalciol. Image:Calcidiol2.svg|
