== Publication Abstract from PubMed ==
 +
Cell-wall invertases play crucial roles during plant development. They hydrolyse sucrose into its fructose and glucose subunits by cleavage of the alpha1-beta2 glycosidic bond. Here, the structure of the Arabidopsis thaliana cell-wall invertase 1 (AtcwINV1; gene accession code At3g13790) is described at a resolution of 2.15 A. The structure comprises an N-terminal fivefold beta-propeller domain followed by a C-terminal domain formed by two beta-sheets. The active site is positioned in the fivefold beta-propeller domain, containing the nucleophile Asp23 and the acid/base catalyst Glu203 of the double-displacement enzymatic reaction. The function of the C-terminal domain remains unknown. Unlike in other GH 32 family enzyme structures known to date, in AtcwINV1 the cleft formed between both domains is blocked by Asn299-linked carbohydrates. A preliminary site-directed mutagenesis experiment (Asn299Asp) removed the glycosyl chain but did not alter the activity profile of the enzyme.
