    • 10. To demonstrate covalent labeling of the enzyme, we have synthesized an analogue of peptide 5 in which the ethoxy group of the ester has been replaced with biotin hydrazide. This also inactivates the enzyme, and we have demonstrated stable covalent attachment of the label to the enzyme (both subunits) by SDS PAGE followed by western blotting and visualization of biotin-labeled protein with horseradish peroxidase conjugated streptavidin and the Pierce SuperSignal substrate.
