Autophosphorylation activity of histidine-kinases (HK) reconstituted into liposomes has been successfully employed in the Sperandio laboratory to study the response of HKs to chemical cues (1, 2). One of the challenges of performing autophosphorylation assays with membrane-bound HKs is the purification of functional proteins for liposome loading and reconstitution. In this protocol, we describe the liposome reconstitution of the multi-transmembrane domain HK FusK of Enterohemorrhagic Escherichia coli (EHEC) O157:H7, and in vitro autophosphorylation activity in response to L-fucose (5).
