FIGURE 4

Molecular interactive illustration showing the interaction of redocked standard ligands with homology models of the two allelic Eqca-DR. (A) hemagglutinin (HA) and (B) endogenous peptide A2 (A2). 2D chemical structure represents the ligand surrounded by interactive MHCII binding groove residues. P-1, P1 and P2 anchor residues of HA and A2 and their hydrogen bonding interaction with residues of the binding grooves were circled in red. Two allelic Eqca-DR models examined were Eqca-DRA*00103:DRB2*00101 and Eqca-DRA*00201:DRB2*00101.
