Crystal structure of Sulfurisphaera tokodaii O6-methylguanine methyltransferase C120S variantCrystal structure of Sulfurisphaera tokodaii O6-methylguanine methyltransferase C120S variant
Structural highlights
FunctionOGT_SULTO Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) in DNA. Repairs alkylated guanine in DNA by stoichiometrically transferring the alkyl group at the O-6 position to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated (By similarity). See Also |
