Increased sensitivity to oxidative challenges associated with topA deletion in Escherichia coli.

Y C Tse-Dinh1.   

Abstract

Deletion of topA in Escherichia coli was found to result in a higher level of killing after treatment with either hydrogen peroxide or N-ethylmaleimide. This effect on oxidative challenge response represents a new role for E. coli DNA topoisomerase I in addition to prevention of excessive negative supercoiling of DNA.
