Figure 4: The palmitoyl–CoA binding site of PatA.

(a–d) Four views of PatA-S-C16CoA crystal structure showing the binding mechanism of S-C16CoA. The palmitoyl moiety is deeply buried into the hydrophobic tunnel, whereas the coenzyme A moiety extends outwards through the side of the main groove. The 2mFo-DFc electron density map countered at 1 σ for the palmitate ligand is shown.
