Allosteric regulation of 6-phosphofructo-1-kinase activity of fat body and flight muscle from the bloodsucking bug Rhodnius prolixus

Anais da Academia Brasileira de Ciências, 2007
6-phosphofructo-1-kinase (phosphofructokinase; PFK) activity from Rhodnius prolixus, a haematophagous insect which is usually a poor flyer, was measured and compared in two metabolically active tissues - flight muscle and fat body.

A plasma membrane-associated glycolytic metabolon is functionally coupled to KATP channels in pancreatic α and β cells from humans and mice

Cell Reports, 2023
Summary: The ATP-sensitive K+ (KATP) channel is a key regulator of hormone secretion from pancreatic islet endocrine cells. Using direct measurements of KATP channel activity in pancreatic β cells and the lesser-studied α cells, from both humans and mice,

Metabolite concentrations, fluxes and free energies imply efficient enzyme usage. [PDF]

, 2016
In metabolism, available free energy is limited and must be divided across pathway steps to maintain a negative ΔG throughout. For each reaction, ΔG is log proportional both to a concentration ratio (reaction quotient to equilibrium constant) and to a ...

Fast acting allosteric phosphofructokinase inhibitors block trypanosome glycolysis and cure acute African trypanosomiasis in mice

Nature Communications, 2021
Glycolytic enzymes are challenging drug targets due to their highly conserved active sites and phosphorylated substrates. Here, the authors identify fast acting allosteric inhibitors of Trypanosoma brucei phosphofructokinase that block trypanosome ...

Acclimation responses of Arabidopsis thaliana to sustained phosphite treatments [PDF]

, 2013
Phosphite () induces a range of physiological and developmental responses in plants by disturbing the homeostasis of the macronutrient phosphate. Because of its close structural resemblance to phosphate, phosphite impairs the sensing, membrane transport,

Characterization of the phosphofructokinase gene family in rice and its expression under oxygen deficiency stress

Frontiers in Plant Science, 2013
Plants possess two types of phosphofructokinase proteins for phosphorylation of fructose-6-phosphate, the ATP-dependent phosphofructokinase (PFK) and the pyrophosphate-(PPi) dependent pyrophosphate-fructose-6-phosphate-phosphotransferase (PFP).

Glycolysis Is Dynamic and Relates Closely to Respiration Rate in Stored Sugarbeet Roots

Frontiers in Plant Science, 2017
Although respiration is the principal cause of the loss of sucrose in postharvest sugarbeet (Beta vulgaris L.), the internal mechanisms that control root respiration rate are unknown. Available evidence, however, indicates that respiration rate is likely

Hefe‐Phosphofructokinase [PDF]

European Journal of Biochemistry, 1970
The effect of trypsin treatment with respect to the allosteric properties of yeast phosphofructokinase as well as its molecular weight has been studied. In the presence of fructose 6‐phosphate trypsin desensitizes yeast phosphofructokinase to ATP inhibition.
