Analysis of exoprotease production by strains expressing DegU protein variants. (A) Exoprotease production of 3610 (wild type strain), degS (NRS1358), degU (NRS1314), degU + P hyspank -degU (H12L)-lacI (NRS1325) and ΔdegSU + P hyspank -degU (H12L)-lacI (NRS4419) grown on LB agar plates containing 1.5% milk in the absence (−) or presence (+) of 50 μM IPTG. (B) Exoprotease production of 3610 (wild type strain), degU + P hy-spank -degU (H12L, D56N)-lacI (NRS4762) and ΔdegSU + P hy-spank -(H12L, D56N)-lacI (NRS4761) grown on LB agar plates containing 1.5% milk in the absence (−) or presence (+) of 50 μM IPTG. Plates were photographed after 16 h incubation at 37°C.
