Acarbose is a well-known inhibitor of α-glucosidases, α-amylases, cyclomaltodextrin glucanyltransferase (CGTase), and dextransucrase. Bacillus stearothermophilus maltogenic amylase (BSMA) was found to hydrolyze acarbose to give acarviosine-glucose plus glucose and to carry out a transglycosylation reaction to give isoacarbose. Acarviosine-glucose was a potent inhibitor of baker’s yeast α-glucos...
