Fig. 2From: TMalphaDB and TMbetaDB: web servers to study the structural role of sequence motifs in α-helix and β-barrel domains of membrane proteinsBend angle of TM α-helices. Average bend angle of TM helices containing P (left panel;n = 349, “P” search) and PP (right panel; n = 8, “PP” search). Motifs located 4 positions from either the beginning/end of the TM domain or/and containing Pro/Gly within 4 residues of the motif were excludedBack to article page
