Introduction

Overall Structure

- Asymmetric dimer
- Consists of α-helices, β-sheets (mostly on one side of the molecule) with a heme buried inside the protein
- Two molecules of 2-hydroxypropyl-β-cyclodextrin are found near the dimer interface


Binding Interactions

Secondary Structure -catalyzes initial step for converting vitamin D into 25-hydroxyvitamin D -mutation causes rickets-25-hydroxylase deficiency -has closed conformation, substrate access channel mostly covered -secosteroid binding, extended active site


Additional Features

This molecule has a heme which is bound to iron, which, combined with its structural conformation, allows for hydroxylation with the attached substrate. This molecule carries out important functions and is not species or sex specific.
