Cytochrome P450, family 6, also known as CYP6, is a
cytochrome P450
Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that functions as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compo ...

In the fields of molecular biology and genetics, a genome is all the genetic information of an organism. It consists of nucleotide sequences of DNA (or RNA in RNA viruses). The nuclear genome includes protein-coding genes and non-coding ...
. CYP6 and
CYP9, another insect CYP family, belong to the same clan as mammalian
CYP3 and
CYP5 families.
The first two CYP6 subfamilies represented by ''CYP6A1'' and ''CYP6B1'' shared only 32.7% identity, less than the typical CYP subfamilies, which share at least 40% amino acid identity.

Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecule ...
