energy transducer TonB [Bacteroides xylanisolvens]
Protein Classification
energy transducer TonB( domain architecture ID 11435256)
energy transducer TonB interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates such as cobalamin, and various iron compounds (such as iron dicitrate, enterochelin, aerobactin, etc.)

Gram-negative bacterial TonB protein C-terminal; The TonB_C domain is the well-characterized C-terminal region of the TonB receptor molecule. This protein is bound to an inner membrane-bound protein ExbB via a globular domain and has a flexible middle region that is likely to help in positioning the C-terminal domain into the iron-transporter barrel in the outer membrane. TonB_C interacts with the N-terminal TonB box of the outer membrane transporter that binds the Fe3+-siderophore complex. The barrel of the transporter, consisting of 22 beta-sheets and an inside plug, binds the iron complex in the barrel entrance.

TonB family C-terminal domain; This model represents the C-terminal of TonB and is homologs. TonB is an energy-transducer for TonB-dependent receptors of Gram-negative bacteria. Most members are designated as TonB or TonB-related proteins, but a few represent the paralogous TolA protein. Several bacteria have up to four TonB paralogs. In nearly every case, a proline-rich repetive region is found N-terminal to this domain; these low-complexity regions are highly divergent and cannot readily be aligned. The region is suggested to help span the periplasm.
