WebRecent studies suggest that ethenocytosine is repaired by the base excision repair pathway with the ethenobase being removed by thymine-DNA glycosylase. Here single turnover kinetics have been used to compare the excision of ethenocytosine by thymine-DNA glycosylase with the excision of thymine. WebExocyclic ethenobases are highly mutagenic DNA lesions strongly implicated in inflammation and vinyl chloride-induced carcinogenesis. While the alkyladenine DNA glycosylase, AAG (or MPG), binds the etheno lesions 1,N 6-ethenoadenine (ɛA) and 3,N 4-ethenocytosine (ɛC) with high affinity, only ɛA can be excised to initiate base excision … WebAug 1, 1998 · 3,N4-ethenocytosine, a Highly Mutagenic Adduct, is a Primary Substrate for Escherichia coli Double-Stranded Uracil-DNA Glycosylase and Human Mismatch-Specific Thymine-DNA Glycosylase Project:... flower mound nutrition consultant
