Covalently bound substrate at the regulatory site triggers allosteric enzyme activation [PDF]

open access: yes, 2008
The mechanism by which the enzyme pyruvate decarboxylase from yeast is activated allosterically has been elucidated. A total of seven three-dimensional structures of the enzyme, of enzyme variants or of enzyme complexes form two yeast species (three of ...

Incomplete Wood-Ljungdahl pathway facilitates one-carbon metabolism in organohalide-respiring Dehalococcoides mccartyi. [PDF]

open access: yes, 2014
The acetyl-CoA "Wood-Ljungdahl" pathway couples the folate-mediated one-carbon (C1) metabolism to either CO2 reduction or acetate oxidation via acetyl-CoA.

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Structure and functional characterization of pyruvate decarboxylase from Gluconacetobacter diazotrophicus [PDF]

open access: yes, 2014
BACKGROUND: Bacterial pyruvate decarboxylases (PDC) are rare. Their role in ethanol production and in bacterially mediated ethanologenic processes has, however, ensured a continued and growing interest.

PIK‐III‐Mediated Elevation of Thiamine Re‐Sensitises Renal Cell Carcinoma to Cuproptosis via Activating PDHA1

open access: yesCell Proliferation, EarlyView.
PIK‐III enhancing the efficacy of cuproptosis to kill renal cancer cells through dysregulating thiamine metabolism and dephosphorylation of pyruvate dehydrogenase complex E1 (PDHA1), providing a potential option for treatment of cuproptosis‐resistant renal cancer by the combination of PIK‐III and elesclomol.

Optimization of carbon and nitrogen utilization for enhanced photosynthesis, biomass and yield by coexpression of phosphoenolpyruvate carboxylase, aspartate aminotransferase and glutamine synthetase in Brassica juncea

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Coexpression of genes involved in carbon (C) and nitrogen (N) metabolism offers a promising avenue for improving crop yield. This study investigated the impact of coexpressing phosphoenolpyruvate carboxylase [ZmPEPC (P)], aspartate aminotransferase [GmAspAT (A)] and glutamine synthetase [NtGS (G)] in Brassica juncea to enhance plant yield ...

Chronic Inhibition of Mitochondrial Dihydrolipoamide Dehydrogenase (DLDH) as an Approach to Managing Diabetic Oxidative Stress

open access: yesAntioxidants, 2019
Mitochondrial dihydrolipoamide dehydrogenase (DLDH) is a redox enzyme involved in decarboxylation of pyruvate to form acetyl-CoA during the cascade of glucose metabolism and mitochondrial adenine triphosphate (ATP) production.

Coexistence of Wolbachia with Buchnera aphidicola and a secondary symbiont in the aphid Cinara cedri.

open access: yes, 2004
Intracellular symbiosis is very common in the insect world. For the aphid Cinara cedri, we have identified by electron microscopy three symbiotic bacteria that can be characterized by their different sizes, morphologies, and electrodensities.

Expanded roles of pyruvate-sensing PdhR in transcription regulation of the Escherichia coli K-12 genome: fatty acid catabolism and cell motility

open access: yesMicrobial Genomics, 2020
The transcription factor PdhR has been recognized as the master regulator of the pyruvate catabolism pathway in Escherichia coli , including both NAD-linked oxidative decarboxylation of pyruvate to acetyl-CoA by PDHc (pyruvate dehydrogenase complex) and ...
