Histidine kinase-like ATPase domain of two-component sensor histidine kinases similar to Escherichia coli YpdA, YehU, Bacillus subtilis LytS, and some hybrid sensor histidine kinases
This family includes the histidine kinase-like ATPase (HATPase) domains of various two-component sensor histidine kinase (HKs) such as Bacillus subtilis LytS, a HK of the two-component system (TCS) LytS-LytR needed for growth on pyruvate, and Staphylococcus aureus LytS-LytR TCS involved in the adaptation of S. aureus to cationic antimicrobial peptides. It also includes the HATPase domains of Escherichia coli YpdA and YehU, HKs of YpdA-YpdB and YehU-YehTCSs, which are involved together in a nutrient sensing regulatory network. Proteins having this HATPase domain also contain a histidine kinase domain (His-kinase), some having accessory sensor domain(s) such as Cache, HAMP or GAF; some are hybrid sensor histidine kinases as they also contain a REC signal receiver domain.
