Abstract
3-(2-Carboxyethyl)-4,6-dichloro-1H-indole-2-carboxylic acid (MDL-29951), an antagonist of the glycine site of the NMDA receptor, has been found to be an allosteric inhibitor of the enzyme fructose 1,6-bisphosphatase. The compound binds at the AMP regulatory site by X-ray crystallography. This represents a new approach to inhibition of fructose 1,6-bisphosphatase and serves as a lead for further drug design.

Abstract
Structural changes during the R-to-T transition of fructose-1,6-bisphosphatase (EC 3.1.3.11) form a hierarchy, in which structural changes at one level are supported by those at the other levels. The quaternary conformational changes involve a 17 degrees rotation between the upper and lower dimers, and a 3.4 degrees rotation between monomers in a dimer. Within monomers, the FBP domain, which remains rigid during the R-to-T transition, rotates 2.3 degrees relative to the AMP domain, which undergoes significant structural reorientations. The most important of these reorientations are the newly identified partially ordered loop residues 55-61 in the T state and reorientations of helices H1, H2, and H3. Supporting these structural changes are numerous readjustments of hydrogen bonding and van der Waals interactions throughout the entire tetrameric protein. Propagation of structural changes during the R-to-T transition relies primarily on helices H1, H2, H3, and loop 50-72. The change that begins at the AMP site causes reorientation of H1, H2, and H3 and changes of interactions across the C1-C4 (C2-C3) interface. These changes may propagate down H1, H2, H3, and loop 50-72 to affect interactions across the C1-C2 (C3-C4) and C1-C3 (C2-C4) interfaces. AMP inhibition is most probably caused by reduced metal binding affinity due to structural changes of metal ligands (Glu97, Asp118, and Asp121) in the active site. The eight-stranded beta-sheet, particularly the beta-strand B3, which connects Lys112 and Tyr113 of the AMP site with Asp118 and Asp121 of the metal site, may be responsible for communication between the AMP and active sites. Additional structural changes that support such communication include reorientation of the FBP domain and H1, H2, and H3 relative to the eight-stranded beta-sheet, and new conformations of loop 54-72 in the T state as AMP binds.

Abstract
The crystal structure of fructose-1,6-bisphosphatase (EC 3.1.3.11) complexed with fructose 6-phosphate, AMP, and Mg2+ has been solved by the molecular replacement method and refined at 2.5-A resolution to a R factor of 0.215, with root-mean-square deviations of 0.013 A and 3.5 degrees for bond lengths and bond angles, respectively. No solvent molecules have been included in the refinement. This structure shows large quaternary and tertiary conformational changes from the structures of the unligated enzyme or its fructose 2,6-bisphosphate complex, but the secondary structures remain essentially the same. Dimer C3-C4 of the enzyme-fructose 6-phosphate-AMP-Mg2+ complex twists about 19 degrees relative to the same dimer of the enzyme-fructose 2,6-bisphosphate complex if their C1-C2 dimers are superimposed on one another. Nevertheless, many interfacial interactions between dimers of C1-C2 and C3-C4 are conserved after quaternary structure changes occur. Residues of the AMP domain (residues 6-200) show large migrations of C alpha atoms relative to barely significant positional changes of the FBP domain (residues 201-335).

Abstract
The fluorescent nucleotide analogue formycin 5'-monophosphate (FMP) inhibits rabbit liver fructose-1,6-bisphosphatase (I50 = 17 microM, Hill coefficient = 1.2), as does the natural regulator AMP (I50 = 13 microM, Hill coefficient = 2.3), but exhibits little or no cooperativity of inhibition. Binding of FMP to fructose-1,6-bisphosphatase can be monitored by the increased fluorescence emission intensity (a 2.7-fold enhancement) or the increased fluorescence polarization of the probe. A single dissociation constant for FMP binding of 6.6 microM (4 sites per tetramer) was determined by monitoring fluorescence intensity. AMP displaces FMP from the enzyme as evidenced by a decrease in FMP fluorescence and polarization. The substrates, fructose 6-phosphate and fructose 1,6-bisphosphate, and inhibitors, methyl alpha-D-fructofuranoside 1,6-bisphosphate and fructose 2,6-bisphosphate, all increase the maximal fluorescence of enzyme-bound FMP but have little or no effect on FMP binding. Weak metal binding sites on rabbit liver fructose-1,6-bisphosphatase have been detected by the effect of Zn2+, Mn2+, and Mg2+ in displacing FMP from the enzyme. This is observed as a decrease in FMP fluorescence intensity and polarization in the presence of enzyme as a function of divalent cation concentration. The order of binding by divalent cations is Zn2+ = Mn2+ greater than Mg2+, and the Kd for Mn2+ displacement of FMP is 91 microM. Methyl alpha-D-fructofuranoside 1,6-bisphosphate, as well as fructose 6-phosphate and inorganic phosphate, enhances metal-mediated FMP displacement from rabbit liver fructose-1,6-bisphosphatase.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Fructose 2,6-bisphosphate inhibited all three fructose-1,6-bisphosphatases from the liver, intestine, and muscle of the mouse. The sensitivity of the liver enzyme to the inhibitor was significantly diminished when Mg2+ was replaced by Mn2+ as the activating cation. Inhibition of the liver enzyme by fructose 2,6-bisphosphate decreased as the concentration of the metal activator, Mn2+ or Mg2+, increased. The respective I50 values obtained by extrapolation of metal ion concentrations to zero were 40 microM with Mn2+ and 0.25 microM with Mg2+. The extent of desensitization to either fructose 2,6-bisphosphate or AMP inhibition by Mn2+ decreased in the order of the liver, intestine, and muscle enzyme. Only in the case of the liver enzyme was the substrate cooperativity induced by fructose 2,6-bisphosphate in the presence of Mg2+. In all three isoenzymes from the mouse, fructose 2,6-bisphosphate greatly potentiated the AMP inhibition of the enzyme in the presence of either Mg2+ or Mn2+. The liver enzyme with Mn2+ in addition to Mg2+ was still active in the presence of less than 1 microM fructose 2,6-bisphosphate, even though AMP was present at 100-200 microM.

Abstract
The binding of two paramagnetic probes within a subunit of fructose bisphosphatase, viz., Mn2+ at a structural site and a nitroxide spin-label at a sulfhydryl site, has permitted the measurement of NMR and electron paramagnetic resonance (EPR) relaxation rates to map the active and allosteric site topography. Distances from these loci to the phosphoryl of fructose 6-phosphate (Fru-6-P) and inorganic phosphate (Pi) and four nuclei of adenosine 5'-phosphate (AMP) (the phosphorus nucleus, H-8, H-2, and H-1') were obtained. These measurements located the Mn2+ approximately equidistant from the two phosphoryl moieties of the product ligands Fru-6-P and Pi and in close proximity to the AMP. The adenosine moiety of the latter is oriented anti. Analysis of EPR data revealed that the nitroxide group is approximately 16 A from the structural Mn2+ site. Calculation of the residence times for the hydrolysis reaction products suggests that their dissociation should not be rate limiting in the overall reaction cycle.

Abstract
1. The activity of beef liver fructose bisphosphatase has been shown to respond cooperatively to increasing concentrations of the activating cations Mg2+ and Mn2+. The allosteric inhibitor AMP caused an increase in this cooperativity and a decrease in the apparent affinity of the enzyme for the activating cation. 2. The cooperative response of the enzyme to AMP is similarly increased by increasing cation concentrations with a concomitant decrease in the apparent affinity. 3. Direct binding experiments indicated that in the absence of either Mg2+ or Mn2+ the enzyme bound AMP non-cooperatively up to a maximum of two molecules per molecule of enzyme, a result that is indicative of half-sites reactivity. The binding became increasingly cooperative as the concentration of the activating cation was increased. 4. The substrate fructose bisphosphate had no effect on any of these cooperative responses. 5. These results may be most simply interpreted in terms of concerted model in which the activating cation functions both as an allosteric activator and as an essential cofactor for the reaction.

Abstract
1. The kinetics of the reaction catalysed by fructose bisphosphatase have been studied at pH 7.2 and at pH 9.5. The activity of the enzyme was shown to respond sigmoidally to increasing concentrations of free Mg2+ or Mn2+ ions at pH 7.2, whereas the dependence was hyperbolic at pH 9.5. At both pH values the enzyme responded hyperbolically to increasing concentrations of fructose 1,6-bisphosphate, although inhibition was observed at higher concentrations of this substrate. This high substrate inhibition was shown to be partial in nature and the enzyme was found to be more sensitive at pH 7.2 than at pH 9.5. 2. The properties of the enzyme, are consistent with the enzyme obeying either a random-order equilibrium mechanism or a compulsory-order steady-state mechanism in which fructose bisphosphate binds to the enzyme before the cation. 3. Reaction of the enzyme with a four-fold molar excess of p-chloromercuribenzoate caused activation of the enzyme when its activity was assayed in the presence of MN2+ ions but inhibition when Mg2+ ions were used. Higher concentrations of p-chloromercuribenzoate caused inhibition. This activation at low p-chloromercuribenzoate concentrations, and the reaction of 5,5'-dithio-bis(2-nitrobenzoate) with the four thiol groups in the enzyme that reacted rapidly with this reagent, were prevented or slowed by the presence of inhibitory, but not non-inhibitory, concentrations of fructose bisphosphate. After reaction with a four-fold molar excess of p-chloromercuribenzoate the enzyme was no longer sensitive to high substrate inhibition by fructose bisphosphate.
