text: Additionally, the rate of product formation for many enzymes (e.g. proteases, nucleases, etc) can be followed by FRET using model substrates where a donor and acceptor fluorophore are attached at the ends of the target substrate molecule and cleavage is scored as a loss in energy transfer as the substrate molecule is split (4857).
