A unique method is described for directly observing the lateral organization of a membrane protein (bacterial light-harvesting complex LH2) in a supported lipid bilayer using total internal reflection fluorescence (TIRF) microscopy. The supported lipid bilayer consisted of anionic 1,2-dioleoyl-sn-glycero-3-[phospho-rac-(1'-glycerol)] (DOPG) and(More)
The PufX protein, encoded by the pufX gene of Rhodobacter sphaeroides, plays a key role in the organization and function of the core antenna (LH1)-reaction centre (RC) complex, which collects photons and triggers primary photochemical reactions. We synthesized a PufX/maltose-binding protein (MBP) fusion protein to study the effect of the PufX protein on the(More)
