The Lysenin Family [Function: Non-specific channels] Seed alignment | Full alignment in OMPdb

Lysenin is a PFT of Eisena fetida and a member of the aerolysin family. It is a nonamer and forms an 18-strand smooth-walled tubular beta barrel attached to the outside by the C-terminal domains. It is a mushroom-like structure which has a transmembrane pore with a central stem built of a long beta barrel. Having a uniform and stable beta barrel through the entire length of protein makes lysenin an exception among PFTs.
