FRUCTOSE-1,6-BISPHOSPHATASE (D-FRUCTOSE-1,6-BISPHOSPHATE 1-PHOSPHOHYDROLASE) COMPLEXED WITH THALLIUM IONS (10 MM)
Overview
Fructose-1,6-bisphosphatase (Fru-1,6-Pase; D-fructose-1,6-bisphosphate, 1-phosphohydrolase, EC 3.1.3.11) requires two divalent metal ions to, hydrolyze alpha-D-fructose 1,6-bisphosphate. Although not required for, catalysis, monovalent cations modify the enzyme activity; K+ and Tl+ ions, are activators, whereas Li+ ions are inhibitors. Their mechanisms of, action are still unknown. We report here crystallographic structures of, pig kidney Fru-1,6-Pase complexed with K+, Tl+, or both Tl+ and Li+. In, the T form Fru-1,6-Pase complexed with the substrate analogue, 2,5-anhydro-D-glucitol 1,6-bisphosphate (AhG-1,6-P2) and Tl+ or K+ ions, three Tl+ or K+ binding sites are found. Site 1 is defined by Glu-97, Asp-118, Asp-121, Glu-280, and a 1-phosphate oxygen of AhG-1,6-P2; site 2, is defined by ... [(full description)]
