This domain is found in Formamidopyrimidine-DNA glycosylase-like from Arabidopsis thaliana (Fpg) and similar proteins from plants. Fpg is involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. It catalyses the hydrolysis of the N-glycosylic bond between the damaged base and the deoxyribose (glycosylase activity) before cleaving the DNA backbone (lyase activity). This entry represents the C-terminal domain, which shows four alpha- helices, two of them forming the helix-two-turn-helix (H2TH) motif, and two antiparallel beta-strands involved in a structural motif mimicking an antiparallel beta-hairpin zinc finger [1].
Formamidopyrimidine-DNA glycosylase (Fpg) is a DNA repair enzyme that excises oxidised purines from damaged DNA. This family is the central domain containing the DNA-binding helix-two turn-helix domain [1].
