== Publication Abstract from PubMed ==
 +
For the first time, the thioglycoligase strategy has been successfully applied to alpha-glycosidases. The alpha-thioglycoligases derived from the family 31 glycosidases, alpha-xylosidase from E. coli (YicI) and alpha-glucosidase from Sulfolobus solfataricus, catalyze thioglycoligase reactions using alpha-glycosyl fluorides and deoxythioglycosides as donors and acceptors, respectively, in yields up to 86%. In addition, we describe the Michaelis complex of YicI using one of the thioglycosides as a nonhydrolyzable substrate analogue and discuss the structural insights this yields into the specificity and mechanism of family 31 alpha-glycosidases and the molecular basis of an associated genetic disease.
