It consists of 3 S-S bonds. The arrangement of the cysteine pairing was determined as Cys3-Cys40, Cys4-Cys32 and Cys16-Cys26. In addition to the NMR structure (link), a crystal structure has also been solved with the same fold (Acta Cryst 2003; D59: 2125-32). You can rotate, zoom, and view the 3D structure here in the PDB. Another six homologs Vt A1, A2, B, C1, 1-PS, and U-PS have been found to date (see subsequent entries). VtA3 is the most cytotoxic while VtB is the least toxic. MOA: antifungi by membrane targeting and forming channels. Updated 2/2014; 8/2015."
