Secondary Structure Classifications

For the algorithms that accept selectable reference sets, the output that they give is defined by the secondary structure classifications of the reference data. Selection of a reference set is thus made by a consideration of what type of secondary structure definitions are desired and the range of data that is available (310 and Polyproline II helix can only be analysed for with larger wavelength ranges).

The majority of output is given in terms of a 6 classification output devised by Woody and co-workers. For a full description of the classifications see:

Sreerema, N., Venyaminov, S.Y., and Woody, R.W. (1999) Estimation of the number of helical and strand segments in proteins using CD spectroscopy. Protein Sci. 8, 370-380.
αRAlpha helix, regular (helix 1)
αDAlpha helix, distorted (helix 2)
βRBeta sheet, regular (sheet 1)
βDBeta sheet, distorted (sheet 2)

UUnordered

Reference Sets 2 and 5 have different secondary structure definitions and may be used to analyse for 310 helix (SET 2 only) and polyproline II helix. Sets 2 and 5 require data to cover the range 178-260nm.
