Figure 6From: Chelation of Ca2+ ions by a peptide from the repeat region of the Plasmodium falciparum circumsporozoite proteinPeptide conformation S7. Conformation of 1 + Ca with the lowest potential energy and highest agreement with the NMR data determined with the Ca ion in a seven-coordinate environment. (A) Full peptide displaying the Ω-loop involving residues V14-N25. (B) Portion of S7 showing the MD-predicted hydrogen bonds originating γ-turns between residues N21 and D23, P24 and A26, and P24 and N27.Back to article page
