BeStSel (Beta Structure Selection) is a freely accessible webserver for secondary structure determination and fold recognition from protein circular dichroism spectra.

		Single spectrum analysis
		Secondary structure determination distinguishing parallel beta-sheets and antiparallel beta-sheets of different twists, and fold recognition.

		Secondary structure from PDB files
		Eight components of BeStSel and for comparison, DSSP and SELCON3 decomposition are calculated from the PDB file.

		Multiple spectra analysis
		Analysis of a series of spectra as a function of temperature, time, ligand concentration, etc.

		Extinction coefficient calculation
		Calculation of extinction coefficients at 205 nm and at 214 nm based on amino acid sequence and number of disulfide bonds.

		Fold recognition
		Prediction of fold class, architecture, topology and homology for the provided secondary structure contents.

		Disordered-Ordered Classification
		Binary disorder-order classification by analysing far-UV CD data.

		Thermal denaturation analysis
		Analysis of thermal denaturation curve (CD values in a given wavelength) with a two-state model.
