Mapping the interactions of Lys28 from Aβ42 with S100B residues. (a) Structural representation of the Aβ42:S100B complex highlighting the important role of Lys28 (yellow) and distances to nearby residues Met79 (pink, 0.74 nm), Thr82 (green, 0.37 nm) and Glu (blue, 0.58 nm). (b) Probability density distributions of minimum distances between Lys28 (the terminal amino group) and the hot spot partner residues on the S100B surface.
