Fig. 7From: An immunoinformatics approach to epitope-based vaccine design against PspA in Streptococcus pneumoniaeGraphical illustration of the interacting residues between the vaccine construct and the receptor. A total of 19 residues of the vaccine interacted with 26 residues of the TLR4 receptor. A number of six salt bridges (red line) and 25 hydrogen bonds (blue line) were formed in the docked complexBack to article page
