A cartoon representation of the backbone of NTHi P6 (PDB ID 2AIZ) is oriented vertically, with residue 59 highlighted in space-fill (left). Because the OM is measured between 7.5–10 nm thick, and P6 is proposed to interact with monoclonal antibodies on the cell surface via residue 59 (pink), it is unlikely that P6 is long enough to span the OM such that it can also interact with the peptidoglycan layer.
