Effects of the umuDC, mucAB, and samAB operons on the mutational specificity of chemical mutagenesis in Escherichia coli: I. Frameshift mutagenesis.

Mutation research - 1 Jan 1994

Watanabe M, Nohmi T, Ohta T

Abstract excerpt

The specificity of frameshift mutations induced by several classes of chemical mutagens was determined using a collection of mutant E. coli lacZ genes. This collection can detect each of five kinds of specific frameshift events by scoring Lac+ revertant colonies. In addition, the mutational spectra were characterized in backgrounds carrying plasmids that encode the umuDC, mucAB, or samAB operon. 4-Nitroquinoline...
