  • Title: Degradation of bacteriophage lambda deoxyribonucleic acid in vitro by sulfur mustard.
    Author: Venkateswaran N, Malhotra RC, Venkateswaran KS.
    Journal: Biochem Mol Biol Int; 1994 Oct; 34(3):429-35. PubMed ID: 7833820.
    Abstract:
    The degradation of bacteriophage lambda (lambda) deoxyribonucleic acid (DNA) by interaction with 0.1, 0.5 and 1 mM concentrations of sulfur mustard (SM) was investigated using agarose gel electrophoresis. Alkaline agarose gel electrophoresis also revealed single strand breaks at 0.5 and 0.1 mM concentrations of SM. The presence of magnesium ions in the reaction mixture prevented DNA degradation. It is proposed that the degradation of lambda DNA by its interaction with an excess of SM may be caused by the breakage of phosphodiester backbone of DNA via the formation of an intermediate phosphotriester bond.
