ALPHA-L-FUCOSIDASE BELONGS TO GLYCOSYL HYDROLASASE FAMILY 29. THE ENZYME PERFORMS CATALYSIS WITH ...ALPHA-L-FUCOSIDASE BELONGS TO GLYCOSYL HYDROLASASE FAMILY 29. THE ENZYME PERFORMS CATALYSIS WITH RETENTION OF CONFIGURATION AT THE ANOMERIC CARBON. THE COORDINATES GIVEN DEFINE THE STRUCTURE OF ALPHA-L-FUCOSIDASE IN COMPLEX WITH 2-DEOXY-2-FLUORO-FUCOSE. TWO SPECIES ARE PRESENT IN THE CRYSTAL, ONE IS THE 2-DEOXY-2-FLUORO-FUCOSYL-ENZYME INTERMEDIATE, WITH 2-DEOXY-2-FLUORO-FUCOSE COVALENTLY BOUND TO THE NUCLEOPHILE ASP 224,THE OTHER SPECIES IS THE REACTION PRODUCT 2-DEOXY-2-FLUORO-FUCOSE BOUND TO THE ACTIVE SITE. THE LATTER HAS UNDERGONE MUTAROTATION AND IS PRESENT AS THE BETA-CONFORMER. THE TWO SPECIES ARE OVERLAPPING AND HAVE BEEN REFINED WITH PARTIAL OCCUPANCY.
