F219W | mutation introduced to allow for fluorescence measurements. At concentrations near the Km value, the substrate fructose 1,6-bispohosphate causes a 15% increase in the intrinsic fluorescence of the mutant | Sus scrofa |
F232W | mutation introduced to allow for fluorescence measurements. The fluorescence emission of the mutant is not altered significantly by the substrate | Sus scrofa |
Inhibitors | Comment | Organism | Structure |
---|---|---|---|
D-fructose 2,6-bisphosphate | the binding of fructose 1,6-bisphosphate induces the appearance of catalytic sites with lower affinity for substrate and lower catalytic activity. The inhibitor, fructose 1,6-bisphosphate, competes with the substrate for the high-affinity sites. Binding of substrate to the low-affinity sites acts as a stapler that prevents dissociation of the tetramer and hence exchange of subunits, and results in substrate inhibition | Sus scrofa |
