Salt bridges and tryptophan cluster at the HdeB dimer interface. The dimer interface has a cluster of four tryptophan residues (W55 and W56 from each subunit). The two intermolecular salt bridges (K48 and E41) are shown. Residues from subunit A are labeled in cyan; those from subunit B are labeled in maroon.
