Specificity of Cathepsin B to Fluorescent Substrates Containing Benzyl Side-Chain-Substituted Amino Acids at P1 Subsite

Abstract
We have determined the kinetic parameters for the hydrolysis by cathepsin B of peptidyl-coumarin amide and intramolecularly quenched fluorogenic peptides with the general structures εNH2-Cap-Leu-X-MCA...
