'''The Vitamin D Binding Site'''

The Vitamin D binding site is located in domain I and contains helices 1 through 6. The binding site is lined with hydrophobic residues that interact with the hydrophobic parts of the vitamin D3 ligand.<scene name='48/483884/Site_where_25ohd3_binds/1'>Hydrogen ~~bonds~~</scene> are formed between, the 25-hydroxyl and tyrosine 32 with a distance of 2.85 angstroms, the 3-hydroxyl and serine 76 with a distance of 3.01 angstroms and methionine 109 with a distance of 3.01 angstroms. Different analogs of the vitamin D3 ligand influence hydrogen bond locations and binding affinities. <scene name='48/483884/Jy_site_where_25ohd3_binds/4'>The JY analog</scene>, for example, has a binding affinity to DBP of 1314, which is much greater compared to the affinity of 25OHD3, which is 667.
