This entry represents a TBP-like domain present in AfAlkA from Archaeoglobus fulgidus. AfAlkA is a glycosylase involved in base excision repair, capable of repairing mutagenic lesions such as N1-methyladenine (m1A) and N3-methylcytosine (m3C) found in DNA.[1].	Domain

This family contains a diverse range of structurally related DNA repair proteins. The superfamily is called the HhH-GPD family after its hallmark Helix-hairpin-helix and Gly/Pro rich loop followed by a conserved aspartate [2]. This includes endonuclease III, EC:4.2.99.18 and MutY an A/G-specific adenine glycosylase, both have a C terminal 4Fe-4S cluster. The family also includes 8-oxoguanine DNA glycosylases such as Swiss:P53397. The methyl-CPG binding protein MBD4 Swiss:Q9Z2D7 also contains a related domain [1] that is a thymine DNA glycosylase. The family also includes DNA-3-methyladenine glycosylase II EC:3.2.2.21 and other members of the AlkA family.	Domain
