ENZYME entry: EC 2.1.1.63

Accepted Name
Methylated-DNA--[protein]-cysteine S-methyltransferase.
Alternative Name(s)
6-O-methylguanine-DNA methyltransferase.
O-6-methylguanine-DNA-alkyltransferase.
Reaction catalysed
DNA (containing 6-O-methylguanine) + protein L-cysteine <=> DNA (without 6-O-methylguanine) + protein S-methyl-L-cysteine
Comment(s)
  • This protein is involved in the repair of alkylated DNA.
  • It acts only on the alkylated DNA (cf. EC 3.2.2.20 and EC 3.2.2.21).
  • This enzyme catalyzes only one turnover and therefore is not strictly catalytic.
