25-гидроксивитамина D 1-альфа-гидроксилаза (VD 1A гидроксилаза), также известная как кальцидиол 1-монооксигеназа или цитохром P450 27B1 (CYP27B1) или просто 1-альфа-гидроксилаза является цитохрома P450 ферментом , который у людей кодируется CYP27B1 геном .

VD 1A гидроксилаза расположена в проксимальном канальце почек и множество других тканей, включая кожу ( кератиноциты ), иммунные клетки, и кость ( остеобласты ).

Реакция

Фермент : катализирует гидроксилирование кальцифедиола витамина до кальцитриола (биоактивная форма D )

кальцидиол + 2 уменьшенный адренодоксин + 2 ч ⁺ + O ₂ ⇌ кальцитриол + 2 окисленного адренодоксина + h ₂ o

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.

• 
  Calcidiol
• 
  Calcitriol

Clinical significance

Loss-of-function mutations in CYP27B1 cause Vitamin D-dependent rickets, type IA.
