Accession | PRU01359 |
Dates | 27-JAN-2023 (Created) 27-JAN-2023 (Last updated, Version 1) |
Data class | Domain |
Predictors | PROSITE; PS52015; TONB_CTD |
Name | TonB C-terminal domain |
Function | The TonB protein plays an essential role in the energy transduction system to drive active transport across the outer membrane (OM) using the proton-motive force of the cytoplasmic membrane of Gram-negative bacteria. The C-terminal domain (CTD) of TonB protein is known to interact with the conserved TonB box motif of TonB-dependent OM transporters, which likely induces structural changes in the OM transporters. |
