Abstract excerpt
Yeast mutants that are sensitive to photoactivated psoralens, named pso mutants, were isolated and described more than 20 years ago. Nine genes responsible for the pso phenotypes were identified and seven of them cloned and molecularly characterized. Of the nine PSO genes of yeast seven apparently encode proteins involved in the repair of DNA lesions generated by photoinduced psoralens and by other mutagens,...
