| PF00593 | TonB dependent receptor-like, beta-barrel (TonB_dep_Rec_b-barrel) | TonB dependent receptor-like, beta-barrel | This entry represents the beta-barrel domain of TonB-dependent receptors, such as BtuB, CirA, FatA, FcuT, FecA, FepA, among others [1]. | Domain | |
| PF07715 | TonB-dependent Receptor Plug Domain (Plug) | TonB-dependent Receptor Plug Domain | The Plug domain has been shown to be an independently folding subunit of the TonB-dependent receptors ([1]). It acts as the channel gate, blocking the pore until the channel is bound by ligand. At this point it under goes conformational changes opens ... | Domain | |
