structure contains a (beta/alpha)8-barrel catalytic domain with B and B' subdomains, an N-terminal domain N, and the C-terminal domains C and D. The N-terminal domain binds a trisaccharide. Complexes of the enzyme with acarbose and 1-dexoynojirimycin and two different covalent glycosyl-enzyme intermediates show that the aspartic acid residues Asp553 and Asp665 are the catalytic nucleophile and acid, respectively. The catalytic nucleophile is in a position to act also as a base that abstracts a proton from the C2 carbon atom of the covalently bound subsite -1 glucosyl residue | Gracilariopsis lemaneiformis |
