Comparison of farnesyl pyrophosphate synthase complexes from P. aeruginosa (PaFPPS; this study) and E. coli (EcFPPS; PDB entry 1rqi
; Hosfield et al., 2004). (a) Stereo representation of part of subunit A of PaFPPS in complex with GPP and Mg2+. Electron density (Fo − Fc OMIT map contoured at 1.0σ) is shown around the bound ligands. Asp83, Asp84 and Asp89 form part of motif I, while Asp222, Asp223 and Asp226 form part of motif II. (b) Stereoview of the active site of EcFPPS in complex with DMSPP (S1 site), IPP (S2 site) and Mg2+. Residue numbering is specific to the respective enzymes. |
