Structure of the P46–FabP46 complex. (a) Ribbon representation of the P46–FabP46 complex. The interaction only involves residues from the C-domain of P46. A xylose molecule bound in the cleft between the two domains of P46 is shown (brown). The N-terminal helix, which is absent in the P46 construct studied, is represented anchored into the membrane to emphasize the likely situation in the C-domain with respect to the mycoplasma membrane. (b) Electron micrographs showing immunogold labelling of the P46 protein on ultrathin frozen sections from M. hyopneumoniae. Yellow arrows indicate gold particles co-localizing with P46. The scale bar represents 0.1 µm. |
