ExbB consists of three transmembrane domains (spanning from residues 16-39, 128-155 and 162-194), with two large portions of the protein representing the majority of the protein in the cytoplasm and two smaller portions in the periplasm | ExbB consists of three transmembrane domains (spanning from residues 16-39, 128-155 and 162-194), with two large portions of the protein representing the majority of the protein in the cytoplasm and two smaller portions in the periplasm<ref name='Kampfenkel'>PMID: 8449962</ref>. | ||
ExbB can exist in the TonB system either in a complex with [[ExbD]] (to a ratio of 3.5:1) or on its own (where no ExbD is present), which has been suggested to play a part in the diverse roles of TonB | ExbB can exist in the [[TonB]] system either in a complex with [[ExbD]] (to a ratio of 3.5:1) or on its own (where no ExbD is present), which has been suggested to play a part in the diverse roles of TonB<ref name='Held'>PMID: 12193634</ref>. | ||
