- Abstract
Two fluorogenic substrates are described for the detection of Penicillin-G-acylase (EC 3.5.1.11) activity in coloured cell-containing media and inside single cells. A sensitive enzyme assay is based on the use of 7-phenylacetyl-4-alkylcoumarinylamides. Linear response is obtained in the range 20-300 μU m-1. After the cells have been made permeable, intracellular enzyme activity can be monitored. It is thus possible to label enzyme-containing cells and to distinguish them from enzyme-free cells by fluorescence microscopy or laser-flow cytometry.
