-
The crystal and molecular structure of the alpha-amylase inhibitor, Hoe-467A has been determined and refined at high resolution. The, polypeptide chain is folded in two triple-stranded sheets, which form a, barrel. The topology of folding is as found in the immunoglobulin domains., The amino acid triplet Trp18-Arg19-Tyr20 has an exceptional conformation, and position in the molecule and is possibly involved in inhibitory, activity.
