Figure 3
Final 2mFo − DFc electron-density maps around the bound synthetic glycoclusters. (a) The N-linked glycoclusters NGS, diNGS and diNGT. (b) The S-linked glycoclusters STG, STGD and diSTGD. The orientation is similar for all ligands. The maps (blue mesh) are contoured at the 1.0σ level. The ligands are shown as sticks with C atoms in black, O atoms in red, N atoms in blue and S atoms in yellow. Only ligand portions defined by the electron-density maps are shown. The galactose moiety is labeled for clarity. O atoms of the succinimidyl and tartaramidyl carbonyl groups adjacent to the amide linkage are labeled O1suc and O1tar, respectively. O atoms of the succinimidyl and tartaramidyl carbonyl groups distal to the amide linkage are indicated as O2suc and O3tar, respectively. The O atom of the symmetric isomannide scaffold is labeled O2iso. The O atom of the thioglucose is labeled O2glc. The N and S atoms of the amide and thioglucoside linkages are labeled N1, S1 and S2, respectively. The maps were generated in Phenix (Liebschner et al., 2019  ). |
