Abstract: Human odorant-binding protein, OBPIIa , is expressed by nasal epithelia to facilitate transport of hydrophobic odorant molecules across the aqueous mucus. Here, we report its crystallographic analysis at 2.6 Å resolution. OBPIIa is a monomeric protein that exhibits the classical lipocalin fold with a conserved eight-stranded β-barrel harboring a remarkably large hydrophobic pocket. Basic residues within the four loops that shape the entrance to this ligand-binding site evoke a positive electrostatic potential.…
