✦ Synopsis

The secondary structure of abductin was investigated by CD and NMR studies of several synthetic peptides. Results obtained with these peptides showed the dominant conformations to be the polyproline II (PPII) structure in aqueous solution and different types of b-turns in the less polar solvent trifluoroethanol. Accordingly, a preliminary structure -elasticity relationship for abductin, not unlike that currently accepted for elastin, is proposed. Chirality 17: 364 -372, 2005.
