2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is carcinogenic in multiple organs and numerous species. Bioactivation of PhIP is initiated by PhIP N(2)-hydroxylation catalysed by cytochrome P450s. Following N-hydroxylation, O-acetylation catalysed by N-acetyltransferase 2 (NAT2) is considered a further possible activation pathway. Genetic(More)
Prokaryotic DNA repair nucleases are useful reagents for detecting DNA lesions. UvrABC endonuclease, encoded by the UvrA, UvrB, and UvrC genes can incise DNA containing bulky nucleotide adducts and intrastrand cross-links. UvrA, UvrB, and UvrC were cloned from Bacillus caldotenax (Bca)and UvrC from Thermatoga maritima (Tma), and recombinant proteins were(More)
