Fig. 2. Stereoview of the triabin ribbon. The eight strands A
to H forming the - barrel are
shown as yellow arrows, the N- and the^ C-terminal surface
helices are shown as green helical ribbons, and the connecting
loops are shown as green ropes. A few aromatic^ side chains, as
well as the polar residues involved in the internal salt-bridge
cluster, are shown with all nonhydrogen atoms. The^ view is,
similar as in Fig. 1, approximately along the barrel axis of
triabin i.e.,
through the more narrow barrel opening (front) toward the wider
opening of the calyx (back). The figure was made^ with SETOR (8).
