The percentage distribution of posterior probability ( Q k ) and the localization of sites with Q k > 0.9. 269 sites were investigated in bacterial PBPs and the class C GPCR VFTM domains. A bacterial PBP crystal structure [PDB: 2LIV] was used as the template to model the 3D structures. The arrow represents the ligand-binding pocket region. Sites with Q k > 0.9 are depicted in red.
