Superfamily: Alpha-helical porin B/porin C

This superfamily represents the putative cell wall channel-forming proteins porin B and porin C from Corynebacterium sp. Porin B from Corynebacterium glutamicum (Brevibacterium flavum) allows the exchange of material across the mycolic acid layer, which is the protective nonpolar barrier. Porin B has an alpha helical core structure consisting of four alpha-helices surrounding a nonpolar interior. There is a disulphide bridge between helices 1 and 4 to form a stable covalently bound ring PMID:18462756. The channel of PorB is oligomeric PMID:18462756.
