Description
UV CD is an excellent technique for studying the conformations adopted by proteins and nucleic acids in solution. The far-UV CD spectrum is sensitive to the peptide bond conformation and as a consequence reflects the secondary structure of the protein (alpha-helix, beta-sheet, turn and unordered content). The near-UV CD spectrum (between 320 nm and 250 nm) leads to a signal sensitive to the tertiary structure derived from Trp or Tyr. Information on secondary and tertiary structure elements of proteins can therefore be provided in a variety of experimental conditions.

Description
Fluorimetry is a tool for protein folding/unfolding studies. Tyrosine and tryptophan are used experimentally as protein fluorescent probes, because they give a good fluorescence signal. Therefore, this technique requires proteins having either Trp or Tyr or both.

Description
UV-visible analysis permits the characterization of proteins coordinating several types of co-factors. The analysis of interactions between proteins exchanging cofactors can also be carried out.
