O6-methylguanine-DNA methyltransferase (MGMT)

Definition:

O6-Methylguanine-DNA methyltransferase (MGMT) is a suicide enzyme that repairs the pre-mutagenic, pre-carcinogenic and pre-toxic DNA damage O(6)-methylguanine. It also repairs larger adducts on the O(6)-position of guanine, such as O(6)-[4-oxo-4-(3-pyridyl)butyl]guanine and O(6)-chloroethylguanine.
