ID 2.1.1.n11 DE methylphosphotriester-DNA--[protein]-cysteine S-methyltransferase. CA (2'-deoxyribonucleoside 5'-methylphosphotriester)-DNA + L-cysteinyl- CA [protein] = 2'-deoxyribonucleotide-DNA + H(+) + S-methyl-L-cysteinyl- CA [protein]. CC -!- This protein is involved in the repair of Sp diastereomers of DNA CC methylphosphotriester lesions. CC -!- This enzyme catalyzes only one turnover and therefore is not strictly CC catalytic. CC -!- The enzyme from the bacterium Escherichia coli also has the activity CC of EC 2.1.1.63 while the enzyme from Bacillus subtilis does not.
