The photodissociation dynamics of CH(2)Br(2) was investigated near 234 and 267 nm. A two-dimensional photofragment ion velocity imaging technique coupled with a [2+1] resonance-enhanced multiphoton (REMPI) ionization scheme was utilized to obtain the angular and translational energy distributions of the

Here we confirm and extend our previous studies demonstrating that the mutagenic potency of 1,2-dibromoethane (DBE) and dibromomethane (DBM) is markedly enhanced (not prevented) in bacteria expressing the O6-alkylguanine-DNA alkyltransferase (ATase) encoded by the Escherichia coli ogt gene. We demonstrate

O(6)-Alkylguanine-DNA alkyltransferase (AGT) is a DNA repair protein that removes O(6)-alkylguanine adducts. The interaction of dibromomethane (CH(2)Br(2)) and bromomethyl acetate (BrCH(2)OAc) with AGT was studied in vitro, and the effect of AGT on their toxicity and mutagenicity was investigated using
