Four mutants of Micrococcus radiodurans defective in the ability to repair DNA damaged by mitomycin-C, two of which have wild-type resistance to ultraviolet radiation

Abstract

Four genes concerned with the resistance of wild-type Micrococcus radiodurans to the lethal action of mitomycin-C (MTC), mtcA, mtcB, uvsA and uvsB, have been identified by isolating mutants sensitive to MTC. Two strains of M. radiodurans, 302 and 262 carrying mutations in mtcA and mtcB respectively, are between forty and sixty times as sensitive as the wild… (More)
