Abstract
Cells are described that are useful in rapid, sensitive, and accurate cell-based assays for enzyme activity, particularly for enzyme activities associated with botulinum toxins. Such cell expresses a construct that includes an anchor region, a cleavage site, and a reporting region having two or more identical reporter peptides. Enzymatic activity at the cleavage site releases the reporter region into the cytosol of the cell, where multiple degradation events occur. The observed change in the signal is proportional to the enzymatic activity.
