Figure 3
(a) Perdeuterated L-fucose coordinating two Ca atoms in the binding site of LecB (Gajdos et al., 2022). Calcium ions are shown as purple spheres, metal coordination as solid purple lines (with lengths labelled in Å) and D atoms as yellow sticks. 2mFo − DFc neutron scattering-length density (green mesh) and 2mFo − DFc electron density (blue mesh) are contoured at 1.4σ and 2.2σ, respectively. Reproduced from Gajdos et al. (2022). (b) Using the same orientation as in (a), this shows fucose bound to the protein with the H atoms now determined experimentally (PDB entry 7prg; this figure was obtained using Coot (Emsley et al., 2010). |
