In situ extension as an approach for identifying novel alpha-amylase inhibitors, structure containing maltosyl-alpha (1,4)-D-gluconhydroximo-1,5-lactamIn situ extension as an approach for identifying novel alpha-amylase inhibitors, structure containing maltosyl-alpha (1,4)-D-gluconhydroximo-1,5-lactam
Structural highlights
FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedA new approach for the discovery and subsequent structural elucidation of oligosaccharide-based inhibitors of alpha-amylases based upon autoglucosylation of known alpha-glucosidase inhibitors is presented. This concept, highly analogous to what is hypothesized to occur with acarbose, is demonstrated with the known alpha-glucosidase inhibitor, d-gluconohydroximino-1,5-lactam. This was transformed from an inhibitor of human pancreatic alpha-amylase with a K(i) value of 18 mm to a trisaccharide analogue with a K(i) value of 25 mum. The three-dimensional structure of this complex was determined by x-ray crystallography and represents the first such structure determined with this class of inhibitors in any alpha-glycosidase. This approach to the discovery and structural analysis of amylase inhibitors should be generally applicable to other endoglucosidases and readily adaptable to a high throughput format. In situ extension as an approach for identifying novel alpha-amylase inhibitors.,Numao S, Damager I, Li C, Wrodnigg TM, Begum A, Overall CM, Brayer GD, Withers SG J Biol Chem. 2004 Nov 12;279(46):48282-91.
