英文摘要 | A novel fluorescent peptide substrate, H-2 N-E (Eddnp) STLQSGLK (Abz)-CONH2, based on fluorescence resonance energy transfer(FRET) technique, was designed and synthesized by solid-phase peptide synthesis. Abz/Eddnp was used as the fluorescence donor and quenching pair. The highly fluorescent Abz group was efficiently quenched by energy transfer to the Eddnp group. The fluorescent substrate was specifically hydrolyzed by SARS-CoV 3CL(pro) between QS with 15-fold increase in fluorescence and the cleavage site was determined by HPLC-MS. The studies on its enzymatic kinetics(K-m = 525.5 mu mol/L and K-cat = 1.29 min(-1)) elucidate that the synthetic fluorescent peptide substrate is suited to be used as a fluorescent probe in determination of the activity of SARS-CoV 3CL(pro) and screening assays for its inhibitors. |
