Fig. 6

a Molecular docking of the PspA (clade2) and HLF as control of docking. Two 3D structures of the docked complex of the PspA with HLF have been shown. The surface depictions of the PspA-HLF complex are illustrated using the PyMOL software. The PspA and HLF have been shown in red and green, respectively. b Dimplot interaction plot between PspA (clade 2) residues and HLF molecule in the docked complex as a PDB:2PMS control complex. PspA (Clade2) residues, HLA residues, hydrogen bonds, salt bridge, and non-bonded residues are exhibited in green, blue, blue dashed lines, green dashed lines, and red/pink eyelashes, respectively
