Abstract
Enzyme substrates and associated technology of the present invention are provided. An enzyme substrate of the invention may comprise a biologically functional fluorescent dye and an enzyme-specific substrate moiety attached in such a way that the functionality of the functional dye is diminished. An enzymatic reaction may cleave at least a portion of the substrate moiety from the enzyme substrate to provide a more functional product dye. This product dye may be nonfluorescent or weakly fluorescent, in general, and relatively fluorescent, in a particular condition, such as when bound to a partner biological molecule or an assembly of partner biological molecules. An enzyme substrate of the present invention may thus be useful in fluorescence detection, and/or in any of a variety of useful applications, such as the detection of enzymatic activity in a cell-free system or in a living cell, the screening of drugs, or the diagnosis of disease.
