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 the channel.	Domain

This domain is found at the C-terminal end of BT1760 from Bacteroides thetaiotaomicron and similar bacterial proteins that predominantly belong to the glycoside hydrolase family 32 (GH32). BT1760 is an endo-levanase that requires its C-terminal beta-sandwich domain to fold and function correctly. This domain shows two facing beta-sheets consisting of seven and eight antiparallel beta-strands [1].	Domain
