(a) Interactions of (S)-1,2,4-butanetriol with EtLsc (PDB entry 7oso). The ligand C atoms are coloured green, with EtLsc C atoms in grey, O atoms in red and N atoms in blue. The ligand interacts with the catalytic triad of EtLsc (Asp46, Asp203 and Glu287). (b) Representation of a polder OMIT map calculated with exclusion of the (S)-1,2,4-butanetriol molecule. The polder map is contoured at 5σ. (c) 2FobsFcalc and FobsFcalc electron-density maps of (R)-1,2,4-butanetriol. The FobsFcalc map difference-peak intensities are contoured at 10σ.
