25-Hydroxyvitamin D3 1-alpha-hydroxylase (VD3 1A hydroxylase) also known as cytochrome p450 27B1 (CYP27B1) or simply 1-alpha-hydroxylase is a cytochrome P450 enzyme that in humans is encoded by the CYP27B1 gene.[5][6][7]

VD3 1A hydroxylase is located in the proximal tubule of the kidney and a variety of other tissues, including skin (keratinocytes), immune cells,[8] and bone (osteoblasts).[9] The enzyme catalyzes the hydroxylation of Calcifediol to calcitriol (the bioactive form of Vitamin D):[10]

calcidiol + 2 reduced adrenodoxin + 2 H+ + O2 calcitriol + 2 oxidized adrenodoxin + H2O
calcidiol 1-monooxygenase
