A, B, C, D	PF02518	Histidine kinase-, DNA gyrase B-, and HSP90-like ATPase (HATPase_c)	Histidine kinase-, DNA gyrase B-, and HSP90-like ATPase	This family represents the structurally related ATPase domains of histidine kinase, DNA gyrase B and HSP90.	Domain
A, B, C, D	PF07568	Histidine kinase (HisKA_2)	Histidine kinase	This is the dimerisation and phosphoacceptor domain of a sub-family of histidine kinases [1]. It shares sequence similarity with Pfam:PF00512 and Pfam:PF07536 [2]. It is usually found adjacent to a C-terminal ATPase domain (Pfam:PF02518). This domain ...	This is the dimerisation and phosphoacceptor domain of a sub-family of histidine kinases [1]. It shares sequence similarity with Pfam:PF00512 and Pfam:PF07536 [2]. It is usually found adjacent to a C-terminal ATPase domain (Pfam:PF02518). This domain is found in a wide range of Bacteria and also several Archaea.	Domain
