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 |
