a comparative study of substrate specificity of cathepsin d and high molecular weight aspartic peptidase with the use of fluorescent substrate with inner fluorescence quenching , abz-ala-ala-phe-phe-pna , revealed that both peptidases hydrolyzed the single bond between two phenylalanine residues , resulting in the increase of fluorescence ( 4.5-5-fold ) of anthraniloyl tripeptide .
