Substrate cleavage at the surface. Three SNAP-25-derived substrate candidates immobilized on Au SAMs, peptides flu-SNAP (residues 187–203) and flu-SNAPQ (residues 187–203 with Gln substitution) as well as the recombinant SNAP-25 (rSNAP, residues 141–206), were cleaved by 2 µg/mL ALC over the course of 3 h. All sample groups, n = 4.
