Enzyme Information

2.1.1.63
Methylated-DNA--[protein]-cysteine S-methyltransferase.
based on mapping to UniProt P16455
DNA (containing 6-O-methylguanine) + protein L-cysteine = DNA (without 6-O-methylguanine) + protein S-methyl-L-cysteine.
-!- 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.
