This work in conjunction with the results presented in an earlier report (M. A. Purdy and K. L. Yielding, Antimicrob. Agents Chemother. 10:182--184, 1976) showed the following. (i) Nalidixic acid and novobiocin could inhibit post-ultraviolet and post-X-ray survival, implicating gyrase function in deoxyribonucleic acid repair. (ii) The inhibition of post-ultraviolet survival requires the action of functional recBC deoxyribonuclease. (iii) Structural changes in the gyrase could (a) cause recBC mutants to exhibit enhancement of post-ultraviolet killing in the presence of novobiocin, (b) increase the ultraviolet sensitivity of recBC mutants, and (c) enhance the thermal lability of a recBCts mutant.
