Organisms Xanthomonas campestris pv. campestris
Description we aimed to identifythe physiological substrates of Prc and investigate the role of Prc-catalysed proteolysis in controlling the environmental adaptation of X. campestris pv. campestris, which is more genetically amenable than X. oryzae pv. oryzae. Under osmostress, Prc directly bound and cleaved the sensor region of VgrS, a canonical histidine kinase (HK) controlling bacterial virulence and stress responses. Proteolysis of the VgrS sensor resulted in the inhibition of the autokinase activity of this HK, which caused a reprogramming of VgrS-triggered gene expressions and significantly promoted bacterial resistance to osmostress. Because Prc-like proteases and HKs are signaling proteins commonly distributed in the kingdom of Gram-negative bacteria, the inactivation of HK by periplasmic protease may be a general and important form of cross-talk between two-component signalling systems (TCSs) and proteolysis regulation.
