| DNA containing 6-O-methylguanine + [protein]-L-cysteine | the binding to DNA is the rate determining step in the repair process. Approximately eight base pairs of the DNA substrate are covered by the human enzyme. Binding affinity to methylated DNA is two times higher than that to unmodified DNA. The interaction with DNA induces a conformational change in the enzyme | Homo sapiens | DNA lacking 6-O-methylguanine + [protein]-S-methyl-L-cysteine | - |
