HHsearch alignment for GI: 254780553 and conserved domain: TIGR01083
>TIGR01083 nth endonuclease III; InterPro: IPR005759 The spectrum of DNA damage caused by reactive oxygen species includes a wide variety of modifications of purine and pyrimidine bases. Among these modified bases, 7,8-dihydro-8-oxoguanine (8-oxoG) is an important mutagenic lesion. Base excision repair is a critical mechanism for preventing mutations by removing the oxidative lesion from the DNA. Escherichia coli Nth protein (endonuclease III) has an 8-oxoG DNA glycosylase/AP lyase activity which removes 8-oxoG preferentially from 8-oxoG/G mispairs. Human hNTH1 protein, a homolog of E. coli Nth protein, has similar DNA glycosylase/AP lyase activity that removes 8-oxoG from 8-oxoG/G mispairs . ; GO: 0003906 DNA-(apurinic or apyrimidinic site) lyase activity, 0006284 base-excision repair, 0005622 intracellular.
