The overall structure of LS-24 monomer. A, Amino acid sequence of LS-24 along with secondary structure assignment on the basis of crystal structure. B, Stereo view of ribbon diagram highlighting the β-propeller topology of the protein. The blades of the propeller have been differently colored and marked as I, II, III, and IV, from N to C terminus. C, Surface diagrams of LS-24 displaying differential distribution of charge in two opposite views.
