Figure 5.
Stereoscopic representation of the TSP2 D3 and D4 folds. The polypeptide chain is colored with a rainbow color scheme beginning with blue at the N-terminus and ending in red at the C-terminus of the entire molecule. (a) The D3 β-helix, indicating the two capping α-helices. (b) The D4 β-sandwich. The D4 α-helix is close to the C-terminus of the polypeptide chain and caps the D3 β-helix C-terminus, a feature unique to TSP2.
