crystal structure of Human cytochrome p450

Cytochrome p450: A Brief OverviewEdit

The cytochrome p450 family is a group of enzymes that catalyzes the oxidation of unusual molecules in the body. Most of the time, this occurs with organic molecules thus making them soluble in water. Once soluble in water, the molecule can be flushed out of the body. Most commonly, the oxygen is added in a monooxygenase reaction, which reduces two atoms of dioxygen to one hydroxyl group and one molecule of water. Cytochrome p450's belong to a family of proteins that contain a heme cofactor, making them hemoproteins. These enzymes are extremely diverse and can be found in almost every organism on earth including animals, plants, bacteria, archaea, and even viruses. However, the enzyme has not been found in E. Coli. Over 18,000 different cytochrome p450 proteins have been discovered. Because of the immense diversity, a more focused study on the enzyme cytochrome p450 found specifically in humans will be done throughout the article.  Humans typically produce approximately ~60 different protein variations of cytochrome p450, and I will be focusing on CYP3A4.
