(a) Effects of overproduction of the UvrA protein or the UvrB protein on frequency of illegitimate recombination in the wild type (AB1157). We measured the frequency of formation of λ Spi− phages with or without UV irradiation (50 J/m2 and 100 J/m2), as described in Fig. 1. (b) Effects of overproduction of the UvrA protein or the UvrB protein on the frequency of illegitimate recombination in the recQ mutant. (c) Effects of overproduction of the UvrA protein or the UvrB protein on the frequency of illegitimate recombination in the uvrB mutant. (d) UV sensitivity of the wild-type (AB1157) and the uvrB mutant carrying pBR322, pBR322-uvrA+ (pJA61), or pBR322-uvrB+ (pNP10).
