Figure 4From: Structural and mechanistic investigations on Salmonella typhimurium acetate kinase (AckA): identification of a putative ligand binding pocket at the dimeric interfaceMolecular basis for the substrate and nucleotide specificity of St AckA. (A) Stereo diagram of SCFA binding residues (lime-green) of St AckA with modeled acetate (grey). For comparison, a few superposed residues (teal) of Mt AckA are also shown. (B) Stereo diagram of the putative nucleotide-binding residues (salmon-red) of St AckA and modeled ADP (grey). Distances shown with dashed lines are in Ã….Back to article page
