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

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
