Reduction of sensitivity to ultraviolet light in excision-deficient Escherichia coli strain WP2 uvrA

Mutants with increased resistance to UV light were isolated from Escherichia coli WP2 uvrA. Most of these isolates were designated as true or partial revertants of the uvrA- mutation. However, one class of mutants showed only a moderate increase in resistance to UV. The gene responsible for this phe...

Summary:Mutants with increased resistance to UV light were isolated from Escherichia coli WP2 uvrA. Most of these isolates were designated as true or partial revertants of the uvrA- mutation. However, one class of mutants showed only a moderate increase in resistance to UV. The gene responsible for this phenotypic change is closely linked to the lac locus and has been designated the suuA gene (suppressor of uvrA).
