Figure 5From: Structure of α-conotoxin BuIA: influences of disulfide connectivity on structural dynamicsProline geometries of the BuIA isomers and the sunflower trypsin inhibitor SFTI-1 [26]. The proline residues with trans geometry are marked as t and those with cis as c. The three-dimensional structures of a classic α-conotoxin, ribbon BuIA and SFTI-1 are shown to highlight the structural differences between the various peptides.Back to article page
