Homology model of aquaporins encoded in two strains of Rhodopseudomonas palustris. (A) Superposition of theoretical models of R. palustris water channel proteins from BisB5 (magenta) and CGA009 (cyan) strains. Molecular surfaces (green mesh) clearly illustrate the role of residues F44, H174, T183 and R189 in conferring selectivity towards water molecules in BisB5 (B) and CGA009 (C).
