Background Cyanobacteria can be metabolically engineered to convert CO2 to fuels and chemicals such as ethylene. A major challenge in such efforts is to optimize carbon fixation and partition towards target molecules.

Inhibition of triosephosphate isomerase by phosphoenolpyruvate in the feedback-regulation of glycolysis [PDF]
The inhibition of triosephosphate isomerase (TPI) in glycolysis by the pyruvate kinase (PK) substrate phosphoenolpyruvate (PEP) results in a newly discovered feedback loop that counters oxidative stress in cancer and actively respiring cells.

Enzyme I facilitates reverse flux from pyruvate to phosphoenolpyruvate in Escherichia coli
Enzyme I, a component of the phosphoenolpyruvate-carbohydrate phosphotransferase system (PTS), converts phosphoenolpyruvate to pyruvate. Here, the authors show that Enzyme I facilitates also the reverse reaction during both gluconeogenic and glycolytic ...

Phosphoenolpyruvate carboxykinase in cell metabolism: Roles and mechanisms beyond gluconeogenesis
Background: Phosphoenolpyruvate carboxykinase (PCK) has been almost exclusively recognized as a critical enzyme in gluconeogenesis, especially in the liver and kidney.

Gluconeogenesis is downregulated in hepatocellular carcinoma. Here, the authors show that nuclear receptor Nur77 acts as a tumour suppressor sustaining gluconeogenesis by enhancing phosphoenolpyruvate carboxykinase (PEPCK1) stability via regulating its ...

Allosteric regulation of pyruvate kinase enables efficient and robust gluconeogenesis by preventing metabolic conflicts and carbon overflow [PDF]
Gluconeogenesis, the reciprocal pathway of glycolysis, is an energy-consuming process that generates glycolytic intermediates from non-carbohydrate sources. In this study, we demonstrate that robust and efficient gluconeogenesis in bacteria relies on the

The requirement of phosphoenolpyruvate carboxykinase 1 for angiogenesis in vitro and in vivo
We here examined the potential biological function of phosphoenolpyruvate carboxykinase 1 (PCK1) in angiogenesis. shRNA- or CRISPR-Cas9–induced PCK1 depletion potently inhibited endothelial cell proliferation, migration, sprouting, and tube formation ...

sRNA scr5239 Involved in Feedback Loop Regulation of Streptomyces coelicolor Central Metabolism
In contrast to transcriptional regulation, post-transcriptional regulation and the role of small non-coding RNAs (sRNAs) in streptomycetes are not well studied. Here, we focus on the highly conserved sRNA scr5239 in Streptomyces coelicolor.

Time-resolved crystallography of biomolecules in action has advanced rapidly as methods for serial crystallography have improved, but the large number of crystals and the complex experimental infrastructure that are required remain serious obstacles to ...

Wild-type C. glutamicum ATCC 13032 is known to possess two enzymes with anaplerotic (C4-directed) carboxylation activity, namely phosphoenolpyruvate carboxylase (PEPCx) and pyruvate carboxylase (PCx). On the other hand, C3-directed decarboxylation can be
