Internally quenched fluorogenic substrate for furin.

H Angliker1, U Neumann, S S Molloy, G Thomas.   

Abstract

A new substrate for furin, Abz-Arg-Val-Lys-Arg-Gly-Leu-Ala-Tyr(NO2)-Asp-OH, has been synthesized and characterized. The peptide is an internally quenched fluorogenic substrate. The kinetic parameters are Km = 3.8 microM, kcat = 29.3 s-1, and kcat/KM = 7,710,000 M-1 s-1. The substrate is efficiently cleaved by furin; its kcat/KM value is over 2000-fold higher than that of the commonly used substrate Boc-Arg-Val-Arg-Arg-AMC.
