Abstract: GH29 a-L-fucosidases catalyze the hydrolysis of a-L-fucosidic linkages. Deficiency in human lysosomal a-Lfucosidase (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 a-L-fucosidases from bacteria, mice and man. Crystallographic analysis on bacterial a-L-fucosidase confirms that the ABPs act by covalent modification f the active site nucleophile. Competitive activity-based protein profiling identified L-fuconojirimycin as the single GH29 a-L-fucosidase inhibitor from eight configurational isomers.
