Essential for cell growth and peptidoglycan synthesis. Probably regulated via interaction with FhaA. Homodimer. Interacts with the FHA domain of FhaA. The extendend C-terminal region contains a kinase-like region, which encodes a catalytically inactive pseudokinase, and an extracellular region reminiscent of carbohydrate-binding proteins. Phosphorylated by PknB. Phosphorylation recruits FhaA. In the N-terminal section; belongs to the MurJ/MviN family.
