Figure Legend Snippet: Examples of bnAb recognition of glycans. A. The light chain (dark gray) of 3BNC117 (PDB 5V8L), a CD4bs-directed bnAb, interacts primarily with the core GlcNAc moieties (blue) at the base of the glycan and less with the branched Man glycans (green). Note that the glycans are only resolved to Man-6 with the terminal branching glycans (indicated by arrows) disordered in the cryoEM map. B. The heavy chain (dark gray) of PGT128 (PDB 5ACO), an N332 supersite bnAb, interacts with extended Man-8 (shown) or Man-9 glycans. Because these glycan moieties interact strongly with the bnAb heavy (dark gray) and light (light gray) chains, they are typically well resolved in crystallographic or cryoEM maps. In fact, PGT128 binds high mannose so well that the structure of the Fab and Man-9 alone was solved by crystallography (PDB 3TV3) (103). Man-8 is resolved in the figure shown. C. The heavy chain (dark gray) of PGT151 (PDB 5FUU), a gp120/gp41 interface bnAb interacts with minimally a tri-antennary complex glycan. Glycan array binding data suggest that this N611 glycan may be contain terminal sialic acid residues (indicated by magenta *), but these were not resolved in the cryo-EM map. D. The heavy chain (dark gray) of PG16 (PDB 4DQO) interacts with a terminal sialic acid of a hybrid-type glycan at N173.
