CYP3A4 is a member of the cytochrome P450 superfamily of enzymes. It is one of the most important enzymes in the liver, where it is involved in the metabolism of a wide variety of substrates, including drugs, toxins, and endogenous compounds. CYP3A4 plays a crucial role in the oxidative metabolism of many xenobiotics and is responsible for the catalysis of a range of biotransformation reactions.
