  2. Phosphofructokinase 1 - Wikipedia

    en.wikipedia.org/wiki/Phosphofructokinase_1

    Phosphofructokinase-1 (PFK-1) is one of the most important regulatory enzymes (EC 2.7.1.11) of glycolysis. It is an allosteric enzyme made of 4 subunits and controlled by many activators and inhibitors. PFK-1 catalyzes the important "committed" step of glycolysis, the conversion of fructose 6-phosphate and ATP to fructose 1,6-bisphosphate and ...

  3. Phosphofructokinase - Wikipedia

    en.wikipedia.org/wiki/Phosphofructokinase

    PFK exists as a homotetramer in bacteria and mammals (where each monomer possesses 2 similar domains) and as an octomer in yeast (where there are 4 alpha- (PFK1) and 4 beta-chains (PFK2), the latter, like the mammalian monomers, possessing 2 similar domains [3]). This protein may use the morpheein model of allosteric regulation. [5]

  4. Phosphofructokinase 2 - Wikipedia

    en.wikipedia.org/wiki/Phosphofructokinase_2

    PFK-2 is known as the "bifunctional enzyme" because of its notable structure: though both are located on one protein homodimer, its two domains act as independently functioning enzymes. [5] One terminus serves as a kinase domain (for PFK-2) while the other terminus acts as a phosphatase domain (FBPase-2). [6]

  5. Fructose 2,6-bisphosphate - Wikipedia

    en.wikipedia.org/wiki/Fructose_2,6-bisphosphate

    Fru-2,6-P 2 strongly activates glucose breakdown in glycolysis through allosteric modulation (activation) of phosphofructokinase 1 (PFK-1).Elevated expression of Fru-2,6-P 2 levels in the liver allosterically activates phosphofructokinase 1 by increasing the enzyme’s affinity for fructose 6-phosphate, while decreasing its affinity for inhibitory ATP and citrate.

  6. PFKP - Wikipedia

    en.wikipedia.org/wiki/PFKP

    The PFKP gene encodes the platelet isoform of phosphofructokinase (PFK) (ATP:D-fructose-6-phosphate-1-phosphotransferase, EC 2.7.1.11). PFK catalyzes the irreversible conversion of fructose 6-phosphate to fructose 1,6-bisphosphate and is a key regulatory enzyme in glycolysis. The PFKP gene, which maps to chromosome 10p, is also expressed in ...

  7. Phosphofructokinase deficiency - Wikipedia

    en.wikipedia.org/wiki/Phosphofructokinase_deficiency

    Phosphofructokinase deficiency is a rare muscular metabolic disorder, with an autosomal recessive inheritance pattern. It is characterized as a deficiency in the Phosphofructokinase (PFK) enzyme throughout the body, including the skeletal muscles and red blood cells.

  9. Glucose-1,6-bisphosphate synthase - Wikipedia

    en.wikipedia.org/wiki/Glucose-1,6-bisphosphate...

    Glucose-1,6-bisphosphate is most likely used in correlation with gluconeolysis. The product’s inhibition of hexokinase and activation of PFK-1 and pyruvate kinase is indicative of its role in glycolysis. Glucose-1,6-bisphosphate inhibit hexokinase stopping the production glucose-6-phosphate from D-glucose. Its activation of PFK-1 and pyruvate ...
