Abstract

Abstract Two mutants of Streptomyces cattleya affecting DNA repair were isolated. These mutants were analysed using spore survival curves and phage reactivation curves in the presence and absence of caffeine and arsenite. Two DNA repair systems (uvr1 and uvr2) were identified, the latter of which seems to influence genetic instability.
