Crystal strucure of fructose-1,6-bisphosphatase


Overview

As the first structure of the novel class of fructose-1,6-bisphosphatase (FBPase) present in thermophilic archaea, we solved the crystal structure of the ST0318 gene product (St-Fbp) of Sulfolobus tokodaii strain 7. The St-Fbp structure comprises a homooctamer of the 422 point-group. The protein folds as a four-layer alpha-beta-beta-alpha sandwich with a novel topology, which is completely different from the sugar phosphatase fold. The structure contains an unhydrolyzed FBP molecule in the open-keto form, as well as four hexacoordinated magnesium ions around the 1-phosphoryl group of FBP. The arrangement of the catalytic side chains and metal ligands is consistent with the three-metal ion assisted catalysis proposed for conventional FBPases. The structure provides an insight into the structural basis of the strict substrate specificity of St-Fbp.
