PF07568Histidine kinase (HisKA_2)Histidine kinaseThis 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.
