The structural highlights of this protein are four: the three domains that compose the protein, the binding site in domain II for salicylates, sulfonamides and several drug ingredients, the bilirubin binding site at position 264, and the free cysteine in the structure of the protein <ref> PMID: 32162429</ref>. | The structural highlights of this protein are four: the three domains that compose the protein, the binding site in domain II for salicylates, sulfonamides and several drug ingredients, the bilirubin binding site at position 264, and the free cysteine in the structure of the protein <ref> PMID: 32162429</ref>. | ||
This is the structural view of <scene name='78/781196/3domains/1'>the three domains</scene> by different colors. The shared binding site in domain II between zinc and calcium at residue <scene name='78/781196/273_asp/2'>Asp 273</scene> suggests a crosstalk between zinc and calcium transport in the blood. The <scene name='78/781196/264_bili/1'>bilirubin</scene> binding site at position 264, which is significant because it possess important functions as an antioxidant, but it also serves simply as a means to excrete unwanted heme, derived from various heme-containing proteins such as hemoglobin, myoglobin, and various P450 enzymes. <scene name='78/781196/Cys34/1'>Cys 34</scene> located in a loop between helice is the only cysteine residue that does not participate in any disulfide bridges. Its sulfhydryl group is prevented from coupling with the external counterparts giving a structure known as triclinic crystals. | This is the structural view of <scene name='78/781196/3domains/1'>the three domains</scene> by different colors.
