From: The Yersinia enterocolitica type three secretion chaperone SycO is integrated into the Yop regulatory network and binds to the Yop secretion protein YscM1

Figure 8

SycO overproduction in the mutant strains ΔyscM1 and ΔyscM2 in the presence of calcium ions. Overproduction of SycO was analyzed in Y. enterocolitica parental strain WA-314 and the isogenic deletion mutants ΔyscM1 and ΔyscM2 cultured at 37°C in the presence of 5 mM CaCl2. After 2 h 1 mM IPTG was added and cultivation was continued for another 2 h. Pellet fractions were analyzed by immunoblotting with sera raised aginst YopO, SycO and YopH.
