A plasmid containing the denV gene from bacteriophage T4, under the control of the yeast alcohol dehydrogenase I (ADC1) promoter, conferred a substantial increase in UV resistance in the UV-sensitive Saccharomyces cerevisiae mutants rad1-2 and rad3-2. The UV resistance of the denV+ yeast cells was cell cycle dependent and correlated well with the level of the denV gene product as measured by immunoblotting and by a photoreversal assay for pyrimidine dimer-DNA glycosylase activity.
