CYP3A7 is an enzyme belonging to the cytochrome P450 family. It is 503 amino acids in size and shares 87% of its sequence with CYP3A4. It carries out a similar role in fetuses that CYP3A4 serves in adults. The gene location is 7q22.1. The CYP3A group of
Cytochrome P450, family 3, subfamily A, also known as CYP3A, is a human gene locus. A homologous locus is found in mice. The CYP3A locus includes all the known members of the 3A subfamily of the cytochrome P450 superfamily of genes.

Cytochrome P450 3A4 (abbreviated CYP3A4) ( EC 1.14.13.97) is an important enzyme in the body, mainly found in the liver and in the intestine, which in humans is encoded by CYP3A4 gene. It oxidizes small foreign organic molecules ( xenobiotics ), such as toxins or drugs, so that they can be removed from the body.

CYP3A5 encodes a member of the cytochrome P450 superfamily of enzymes. Like most of the cytochrome P450, the CYP3A5 is expressed in the prostate and the liver.It is also expressed in epithelium of the small intestine and large intestine for uptake and in small amounts in the bile duct, nasal mucosa, kidney, adrenal cortex, epithelium of the gastric...
The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and its expression is induced by glucocorticoids and some pharmacological agents. The enzyme metabolizes drugs such as nifedipine and c...
The (wild-type) CYP3A enzymes have traditionally been thought of as functionally redundant, distinguishable mostly by expression patterns. Since CYP3A5 is almost always expressed at significantly lower levels than CYP3A4, an understanding of its clinical significance was limited. Most studies suggesting any non-overlapping metabolic functions apart...
The CYP3A5 gene has several functional variants, which vary depending on ethnicity. The CYP3A5*1 allele is associated with a normal metabolization of medication. It is most common among individuals native to Sub-Equatorial Africa, though the mutation also occurs at low frequencies in other populations. The CYP3A5*3 allele is linked with a poor meta...
CYP2A7 (cytochrome P450, family 2, subfamily A, polypeptide 7) is a protein that in humans is encoded by the CYP2A7 gene. This gene encodes a member of the cytochrome P450 superfamily of enzymes.
Cytochrome P450. Cytochromes P450 ( P450s or CYPs) are a superfamily of enzymes containing heme as a cofactor that mostly, but not exclusively, function as monooxygenases. [1] However, they are not omnipresent; for example, they have not been found in Escherichia coli. [2] In mammals, these enzymes oxidize steroids, fatty acids, xenobiotics ...
