CYP3A4
From Proteopedia
Overview
Cytochrome P450 3A4 (CYP3A4) is in the heme-thiolate monooxygenases enzyme group meaning the protein contains a heme group with an iron atom. Enzymes in Cytochrome P450 are oxidizing enzymes and CYP3A4 works in the body oxidizing foreign molecules such as toxins and drugs. It appears almost half of the marketed pharmaceutical drugs are metabolized by CYP3A4 [1] All Cytochrome P450 are essential enzymes for metabolism and the sub family 3A4 is the most important. [2] Primarily found in the liver and intestine, CYP3A4 is localized in the endoplasmic reticulum membrane. [3] CYP3A4 plays a role in drug metabolism often aiding deactivation through facilitated excretion from the system or by direct inactivation. [4]
