The secondary structures (α_R to U), performance indices (δ, r), and reference sets are defined in footnotes to Tables 1, 2, and 3, respectively. The results for the corresponding soluble protein reference sets (SP37 and SP43) were obtained by cross-validation analysis and are similar to those of Sreerama and Woody (2000b). The wavelength range of CD spectra was 185 to 240 nm for SP37 and SMP50, and 190 to 240 nm for SP43 and SMP56.
