CD spectra of disordered proteins and some globular proteins with similar spectra. Proteins rich in highly twisted antiparallel β-sheets (colored spectra and corresponding structures) exhibit CD spectra reminiscent of disordered proteins (gray), which makes the distinction between them difficult. Alpha-chymotrypsin (PDB ID: 5CHA), chymotrypsinogen (2CGA), trypsin inhibitor (5PTI), elastase (3EST), ferredoxin (2FDN), ecotin (1ECZ), dUTP pyrophosphatase (1Q5U), and trypsin inhibitor (Kunitz) (1BA7) are shown.
