Near-ultraviolet mutagenesis in superoxide dismutase-deficient strains of Escherichia coli.

Environmental health perspectives - 1 Jan 1994

Knowles R L, Eisenstark A

Abstract excerpt

We compared mutagenic spectra induced by polychromatic near-ultraviolet radiation (near-UV; 300-400 nm) with superoxide anion (O2-) -dependent mutagenesis using a set of Escherichia coli tester strains. Near-UV radiation produced increased frequencies of G:C to A:T transitions, G:C to T:A and A:T to T:A transversions, and small increases in frameshift mutations in wild-type cells. Tester strains lacking...
