Preferred Label : 25-hydroxyvitamin d3 1-alpha-hydroxylase;
MeSH definition : A mitochondrial cytochrome P450 enzyme that catalyzes the 1-alpha-hydroxylation of
25-hydroxyvitamin D3 (also known as 25-hydroxycholecalciferol) in the presence of
molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP27B1
gene, converts 25-hydroxyvitamin D3 to 1-alpha,25-dihydroxyvitamin D3 which is the
active form of VITAMIN D in regulating bone growth and calcium metabolism. This enzyme
is also active on plant 25-hydroxyvitamin D2 (ergocalciferol).;
