Fig. 9. Crystal structure of laspartomycin C (green stick representation) bound to two bound Ca²⁺ ions (orange spheres) and the geranyl monophosphate ligand coordinated by the Ca²⁺ ions. The two Ca²⁺ ions are labelled A (red) and B (blue) with the interacting parts of laspartomycin C responsible for the chelation of the Ca²⁺ ions also indicated.
