Figure 5From: Sequence similarity between the erythrocyte binding domain 1 of the Plasmodium vivax Duffy binding protein and the V3 loop of HIV-1 strain MN reveals binding residues for the Duffy Antigen Receptor for ChemokinesThree dimensional location of heparin binding motif in relation to known binding residues on the crystal structure of recombinant Pkα-DBL. The crystal structure of the recombinant Pkα-DBL that binds to human DARC is shown with previously described binding residues Tyr 94, Asn 95, Lys 96, Arg 103, Leu 168 and Ile 175 [10, 12–14] highlighted in magenta in domain 2 of the molecule. The heparin binding motif on the V3-like peptide is highlighted in yellow cysteines C1-C4 and blue for the basic residues (lysine and arginine) in domain 1 of the molecule.Back to article page
