MGMT-mediated DNA damage reversal
Click the image above or here to open this pathway in the Pathway Browser
Reactive cellular catabolites can cause DNA damage by 6-O-methylation of guanine. 6-O-methylguanine can pair ambiguously with both C and T, and cause transition mutations. Active reversal of such damage can be facilitated by MGMT, a protein that has 6-O-methylguanine-DNA methyltransferase activity (Mitra and Kaina 1993).
