CBIO-15NON-METABOLIC FUNCTION OF PHOSPHOFRUCTOKINASE-1 IN GLIOBLASTOMA MAINTENANCE [PDF]
BACKGROUND: Glioblastoma multiforme (GBM) remains one of the most lethal tumors and is associated with a median survival of only approximately 15 months, despite aggressive combination radio-chemo-therapy. Regardless of recent advances in our understanding of this deadly disease, the molecular mechanisms/genes that cause high recurrence rates and ...

Analysis of phosphofructokinase-1 activity as affected by pH and ATP concentration [PDF]
A key player in energy metabolism is phosphofructokinase-1 (PFK1) whose activity and behavior strongly influence glycolysis and thus have implications in many areas. In this research, PFK1 assays were performed to convert F6P and ATP into F-1,6-P and ADP

Phosphofructokinase 1 Glycosylation Regulates Cell Growth and Metabolism [PDF]
Cancer cells must satisfy the metabolic demands of rapid cell growth within a continually changing microenvironment. We demonstrated that the dynamic posttranslational modification of proteins by O-linked β-N-acetylglucosamine (O-GlcNAcylation) is a key ...

Fructose metabolism in Chromohalobacter salexigens: interplay between the Embden–Meyerhof–Parnas and Entner–Doudoroff pathways [PDF]
Background The halophilic bacterium Chromohalobacter salexigens metabolizes glucose exclusively through the Entner–Doudoroff (ED) pathway, an adaptation which results in inefficient growth, with significant carbon overflow, especially at low salinity ...

Purification and properties of 1-phosphofructokinase from Escherichia coli [PDF]
1-Phosphofructokinase has been purified from Escherichia coli. Size exclusion chromatography revealed an Mr of 57000. After sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) we found a single protein band corresponding to an Mr of 30000. The enzyme was highly specific for fructose-1-phosphate.

Capillary electrophoresis-based assay of phosphofructokinase-1. [PDF]
An assay was developed for phosphofructokinase-1 (PFK-1) using capillary electrophoresis (CE). In the glycolytic pathway, this enzyme catalyzes the rate-limiting step from fructose-6-phosphate and magnesium-bound adenosine triphosphate (Mg-ATP) to fructose-1,6-bisphosphate and magnesium-bound adenosine diphosphate (Mg-ADP).

1-Phosphofructokinase from an Anaerobe
Abstract A soluble 1-phosphofructokinase has been extracted from anaerobic bacteria (Bacteroides symbiosus) and sufficiently purified to reveal its mode of action. The enzyme requires a nucleoside 5'-triphosphate (adenosine, inosine, guanosine, or uridine triphosphate) and magnesium or manganous ions.

Structures of Human Phosphofructokinase-1 and Atomic Basis of Cancer-Associated Mutations [PDF]
Phosphofructokinase-1 (PFK1), the 'gatekeeper' of glycolysis, catalyses the committed step of the glycolytic pathway by converting fructose-6-phosphate to fructose-1,6-bisphosphate. Allosteric activation and inhibition of PFK1 by over ten metabolites and in response to hormonal signalling fine-tune glycolytic flux to meet energy requirements. Mutations

How Phosphofructokinase-1 Promotes PI3K and YAP/TAZ in Cancer: Therapeutic Perspectives. [PDF]
PI3K/AKT is one of the most frequently altered signaling pathways in human cancers, supporting the activation of many proteins sustaining cell metabolism, proliferation, and aggressiveness. Another important pathway frequently altered in cancer cells is the one regulating the YAP/TAZ transcriptional coactivators, which promote the expression of genes ...

The Glycolytic Enzyme Phosphofructokinase-1 Assembles into Filaments [PDF]
Despite abundant knowledge of the regulation and biochemistry of glycolytic enzymes, we have limited understanding on how they are spatially organized in the cell. Emerging evidence indicates that nonglycolytic metabolic enzymes regulating diverse pathways can assemble into polymers.
