Webogy), is rec+ (A kil335 cIts857 P3). The kil mutation was isolated by H. Greer (10). BIK1199 is a A-resistant mutant from M5361. BIK1189 is M5361 cured of A. The recAl strains DH1 and DH5 (11) and plasmid pIK43 were described previously (12). The recombination rate of DHI(pIK43) to Neo+ cells is as low as 4 x 10-7 per cell generation (12). Webrepressor, cIts857, to prevent cell killing. Heat induc- tion of the pL-galR fusion plasmid synthesizes large amounts of active Gal repressor. The protein has been purified to homogeneity in three steps. The purifica- tion is greatly aided by the reversible insolubility of active repressor in crude extract at salt concentrations
