This document summarizes experiments analyzing the activity of various enzymes and inhibitors. It includes graphs showing the effects of inhibitors like tannic acid and 1,10-phenanthroline on pin1 enzyme activity over time, as measured by relative fluorescence units. Another graph shows tannic acid inhibits the glutaminyl cyclase enzyme in a dose dependent manner. The data demonstrates the use of fluorescence-based assays to study enzyme kinetics and screen for small molecule inhibitors.
