development of a FRET peptide substrate, based on the native substrate binding site of human VAMP2 residues 55-94, and evaluation for enzymatic cleavage by the BoNT/B light chain protease, overview. For the synthesis position 74 is mutated to Lys in order to couple 7-methoxycoumarin-4-acetic acid, MCA, to the amine via an amide bond, in part to aid in the flexibility of the MCA to allow free rotation away from the active site and not affect binding and/or cleavage of the peptide. At position 77 the native Phe is replaced with the unnatural amino acid diaminopropionic acid to facilitate coupling of 2,4-dinitrophenyl to the peptide. Thr79 is mutated to a serine increasing kcat 2fold without affecting Km |
