Interactions of the citrate bound at the dimeric interface of Form-II St AckA. Stereo diagram of the putative ligand-binding pocket at the dimeric interface showing bound citrate (CIT-501, magenta). Citrate anchoring residues contributed by subunit-A (pale-yellow) and subunit-B (cyan) are shown in ball and stick representation. Electron density contoured at 1σ (2Fo-Fc) is also shown
