Application

Fructose-6-phosphate kinase from Bacillus stearothermophilus has been used:in steady state analysis of phosphofructokinase activity in the presence of ATP deuterated at the C8 position(C8-D ATP)for standard curve generation for quantifying muscle phosphofructokinase (PFK) activity

Fructose-6-phosphate Kinase from Bacillus stearothermophilus was shown to interact with neuronal nitric oxide synthase (nNOS) causing a defect in glycolytic metabolism and increased fatigability in dystrophic muscle.

Biochem/physiol Actions

Fructose-1,6-bisphosphatase (FBP) is an important enzyme in glucose metabolism. It catalyzes the hydrolysis of fructose-1,6-bisphosphate to fructose-6-phosphate and inorganic phosphate. Fructose-6-phosphate kinase converts fructose-6-phosphate into fructose 1,6-bisphophate in the rate limiting step of the glycolysis cycle.

General description

Fructose-6-phosphate kinase from Bacillus stearothermophilus, a 34 kDa enzyme, belongs to phosphofructokinase (PFK) - like superfamily. The glutamate 161 and arginine 162 residues at the active site are crucial for substrate binding.

Bacillus stearothermophilus phosphofructokinase (BsPFK) is a homotetramer that is allosterically inhibited by phosphoenolpyruvate (PEP), which binds along one dimer-dimer interface.
