Publication Abstract from PubMed
Cyclodextrin glycosyltransferase (CGTase) is an enzyme of the alpha-amylase family, which uses a double displacement mechanism to process alpha-linked glucose polymers. We have determined two X-ray structures of CGTase complexes, one with an intact substrate at 2.1 A resolution, and the other with a covalently bound reaction intermediate at 1.8 A resolution. These structures give evidence for substrate distortion and the covalent character of the intermediate and for the first time show, in atomic detail, how catalysis in the alpha-amylase family proceeds by the concerted action of all active site residues.
