DNA strand scission by benzo[a]pyrene diol epoxides.

H B Gamper, A S Tung, K Straub, J C Bartholomew, M Calvin.   

Abstract

Syn-and anti-benzo[a]pyrene diol epoxides elicit a concentration-dependent nicking of superhelical Col E1 DNA in an in vitro reaction monitored by agarose gel electrophoresis and electron microscopy. This strand scission represents less than 1 percent of the DNA modification by diol epoxide. Kinetic analysis implicates the formation of unstable phosphotriesters, hydrolysis of which nick the DNA.
