With this strucual feature in mind, we have designed a specific inhibitor that contains a chloride group appended to the end of the propyl chain on a known inhibitor termed propyl-NAG-thiazoline. We have shown kinetically that this molecule is a potent suicide inhibitor of this enzyme famiy and now wish to know the precise residue which is acting as the nucleophile to dispace the choride atom.
