Rapid detection of colicin E9-induced DNA damage using Escherichia coli cells carrying SOS promoter-lux fusions.

Abstract:

ColE9 is a plasmid-encoded protein antibiotic produced by Escherichia coli and closely related species that kills E. coli cells expressing the BtuB receptor. The 15-kDa cytotoxic DNase domain of colicin E9 preferentially nicks double-stranded DNA at thymine bases and shares a common active-site structural motif with a variety of other nucleases, including the H-N-H homing endonucleases and the apoptotic CAD proteins of eukaryotes. Studies of the mechanism by which the DNase domain of ColE9 re...
