GH29 α-l-fucosidases catalyze the hydrolysis of α-l-fucosidic linkages. Deficiency in human lysosomal α-l-fucosidase (FUCA1) leads to the recessively inherited disorder, fucosidosis. Herein we describe the development of fucopyranose-configured cyclophellitol aziridines as activity-based probes (ABPs) for selective in vitro and in vivo labeling of GH29 α-l-fucosidases from bacteria, mice and man. Crystallographic analysis on bacterial α-l-fucosidase confirms that the ABPs act by covalent modification of the active site nucleophile. Competitive activity-based protein profiling identified l-fuconojirimycin as the single GH29 α-l-fucosidase inhibitor from eight configurational isomers.
