Abstract
In recB recC sbcB mutants genetic recombination is dependent upon the recF gene. recA801, recA802 and recA803 (formerly called srfA mutations) were originally isolated as mutations that suppress recombination deficiency caused by a recF mutation in a recB recC sbcB genetic background. Since the recA801 mutation also suppressed some of the UV sensitivity due to recF143, we sought to determine what DNA-repair pathways were actually being restored by the recA801 mutation in this genetic background. In this paper we show that the suppression of recF143 by recA801 does not extend to the recF143-mediated defects in induced repair of UV-damaged phages. In addition, we show that recA801 suppresses only slightly the recF143-associated defect in induced expression of the SOS-regulated muc genes of pKM101. These results suggest that recA801 suppresses primarily the RecF pathway of recombinational repair.
