Abstract
Fluorescence techniques are particularly suitable for the study of the interaction between two different proteins, one of which does not possess tryptophan. A fluorescent label attached to such a component may be used as an independent probe of the polarity, symmetry and rigidity of its environment, or as an energy acceptor from tryptophans of the protein molecule with which it interacts. Tryptophan is excited at around 280 nm and has a fluorescence emission spectrum with a maximum around 350 nm. A group with an absorption spectrum which overlaps with this fluorescence spectrum (and which fluoresces at a higher wavelength range) may act as an energy acceptor.
