A gamma -glutamyl tripeptide containing an internally quenched fluorophore has been synthesized and shown to be a substrate for recombinant rat gamma -glutamyl hydrolase. HPLC, LC-MS, and fluorescence spectra support the conclusion that selective hydrolysis occurs at the penultimate peptide bond. Preliminary data indicate that hydrolysis of this substrate can be monitored continuously to yield steady-state kinetic data (C) 2001 Elsevier Science Ltd. All rights reserved.
