'''LEUKOCIDIN F (HLGB) FROM STAPHYLOCOCCUS AUREUS WITH PHOSPHOCHOLINE BOUND'''<br />

==Overview==
Staphylococcal LukF, LukS, HgammaII, and alpha-hemolysin are, self-assembling, channel-forming proteins related in sequence and, function. In the alpha-hemolysin heptamer, the channel-forming, beta-strands and the amino latch make long excursions from the protomer, core. Here we report the crystal structure of the water soluble form of, LukF. In the LukF structure the channel-forming region folds into an, amphipathic, three-strand beta-sheet and the amino latch forms a, beta-strand extending a central beta-sheet. The LukF structure illustrates, how a channel-forming toxin masks protein-protein and protein-membrane, interfaces prior to cell binding and assembly, and together with the, alpha-hemolysin heptamer structure, they define the end points on the, pathway of toxin assembly.

==About this Structure==
