| Primary Identifier | IPR004026 | Type | Domain |
| Short Name | Ada_DNA_repair_Zn-bd |
| description | The Escherichia coli Ada protein repairs O6-methylguanine residues and methyl phosphotriesters in DNA by direct transfer of the methyl group to a cysteine residue. This domain contains four conserved cysteines that form a zinc binding site [, ]. One of these cysteines is a methyl group acceptor. The methylated domain can then specifically bind to the ada box on a DNA duplex. The zinc binding site is located in the N-terminal region and consists of four beta strands []. |
