Conformational rearrangements in the active-site regions of E. coli KAS I. Superposition of monomer A (cyan) of the apo enzyme with (a) apo enzyme, monomer B (magenta), showing the difference in the active-site geometry of the different monomers in the apo structure, (b) enzyme with bound thiolactomycin, monomer A (gold), showing the induced fit upon binding of thiolactomycin, and (c) enzyme with bound aminothiazole ligand, monomer A (green), showing the absence of significant conformational changes upon binding of the aminothiazole ligand. |
