Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013250	Steroid Hydroxylases	Cytochrome P-450 monooxygenases (MIXED FUNCTION OXYGENASES) that are important in steroid biosynthesis and metabolism.	Steroid Hydroxylase,Steroid Monooxygenases,Hydroxylase, Steroid,Hydroxylases, Steroid,Monooxygenases, Steroid
D015090	25-Hydroxyvitamin D3 1-alpha-Hydroxylase	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).	25-Hydroxycholecalciferol 1-Hydroxylase,CYP27B1,Calcidiol 1-Monooxygenase,Cytochrome P-450 CYP27B1,25-Hydroxycholecalciferol-1-Hydroxylase,25-Hydroxyergocalciferol 1-alpha-Hydroxylase,25-Hydroxyvitamin D 1-alpha-Hydroxylase,25-Hydroxyvitamin D(3) 1 alpha-Hydroxylase,25-Hydroxyvitamin D2 1-hydroxylase,1-alpha-Hydroxylase, 25-Hydroxyergocalciferol,1-alpha-Hydroxylase, 25-Hydroxyvitamin D,1-hydroxylase, 25-Hydroxyvitamin D2,25 Hydroxycholecalciferol 1 Hydroxylase,25 Hydroxyergocalciferol 1 alpha Hydroxylase,25 Hydroxyvitamin D 1 alpha Hydroxylase,25 Hydroxyvitamin D2 1 hydroxylase,25 Hydroxyvitamin D3 1 alpha Hydroxylase,Calcidiol 1 Monooxygenase,Cytochrome P 450 CYP27B1
