Proteolysis of SMC at the onset of stationary phase in protease-deficient strains. Lanes "1–4": levels of SMC protein in wild type, clpX or lonA mutant cells during phases 1–4 of growth as indicated in Fig. 5, lane "3+" levels of SMC protein in cell extract from phase 3 to which DNase has been added. Numbers indicate the positions of marker proteins.
