[Advances in phosphatase CheZ of bacterial chemotaxis signaling pathway].

Bacteria get a survival advantages in the complex environment through the chemotaxis system. Chemotaxis plays an important role in colonization and pathogenicity of bacteria, the legume–rhizobia symbiosis, and plant-microbe interactions. Phosphatase CheZ is an indispensable regulatory protein in the process of chemotactic signal adaptation. This review focused on the structure, mechanism of action, functional regulation, protein targeting and the status of the evolutionary of CheZ. This work can benefit the study of other bacterial chemotaxis systems.
