摘要：

We developed a smart activity-based probe that detects the activity of asparaginyl endopeptidase (AEP) in live cells to monitor the dynamics of enzyme regulation. The newly designed probe generated a turn-on fluorescence signal in response to the activity of AEP in living cells without compromising the labelling efficiency or selectivity. Our probe closely reflected the enzyme activity in its native state, detecting subcellular AEP activity in colon cancer cells and neuronal cells.
