Molecular basis for the substrate and nucleotide specificity of St AckA. (A) Stereo diagram of SCFA binding residues (lime-green) of StAckA with modeled acetate (grey). For comparison, a few superposed residues (teal) of MtAckA are also shown. (B) Stereo diagram of the putative nucleotide-binding residues (salmon-red) of StAckA and modeled ADP (grey). Distances shown with dashed lines are in Å.
