Association of PB with secondary structures.

The percentage of different secondary structures (assigned by PROMOTIF) found associated with each PB is given. Only the secondary structures with percentage occurrence greater than 0.5% are given. The PBs are listed in the beginning of each row and the secondary structure type is given as header for each column. Abbreviation of PROMOTIF assignments: BTX – β-turns, X is the type of β-turn, AG – Antiparallel strands, G1 type β-bulge, where the first residue is in the left handed helical conformation (usually Glycine), AC – Antiparallel strands, Classic type beta bulge, one extra residue forms the bulge, GTINV – Inverse γ-turns (φ = −79.0±40,ψ = 69.0±40).
