Structural Insights into the Mechanism of Phosphoenolpyruvate Carboxykinase Catalysis [PDF]

Journal of Biological Chemistry, 2009
Mammalian PEPCK2 catalyzes the reversible formation of PEP from OAA and GTP (or ITP) in a divalent cation-dependent reaction (Scheme 1), as was elegantly discussed in the first minireview of this series on PEPCK (1). SCHEME 1. PEPCK-catalyzed interconversion of OAA and PEP.

CO2 Fertilisation of Growth in Wild C4 Grasses may be Amplified by Upregulated Photosynthesis

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 is expected to have limited direct effects on C4 photosynthesis because the carbon‐concentrating mechanism maintains near‐saturating CO2 at Rubisco. Consequently, growth responses of C4 plants to elevated CO2 (eCO2) are generally attributed to indirect improvements in plant water relations.

Inhibition of ERN1 suppresses the expression of phosphoenolpyruvate carboxykinase 2 in U87MG glioblastoma cells and increases its sensitivity to glucose and glutamine deprivation

Endocrine Regulations
Objective. Phosphoenolpyruvate carboxykinase (PCK) catalyzes the conversion of oxaloacetate to phosphoenolpyruvate and regulates pyruvate metabolism and gluconeogenesis in response to glucocorticoid and insulin stimuli.

Extending the Farquhar–von Caemmerer–Berry photosynthesis model to account for various photorespiratory bypasses

New Phytologist, Volume 252, Issue 3, Page 1327-1342, November 2026.
We extend a widely used C3‐photosynthesis model to account for various photorespiratory bypasses, thereby, providing a useful resource and framework that enforces future novel bypass work and scrutinize if the results go counter to theory. Our model analyses show that of the 17 published bypass pathways, full‐decarboxylating bypasses (that have been ...

Aryl Hydrocarbon Receptor Activation by Dioxin Targets Phosphoenolpyruvate Carboxykinase (PEPCK) for ADP-ribosylation via 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD)-inducible Poly(ADP-ribose) Polymerase (TiPARP)*

Journal of Biological Chemistry, 2013
Background: 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD)-activated aryl hydrocarbon receptor (AHR) decreases gluconeogenesis by suppressing phosphoenolpyruvate carboxykinase (PEPCK) transcription via TCDD-inducible poly(ADP-ribose)-polymerase (TiPARP ...

Metabolic Flux Analysis Reveals Cell Line‐Specific Rewiring in CHO Cells Following TCA Cycle Intermediate Feeding for Bioprocess pH Control

Biotechnology and Bioengineering, Volume 123, Issue 10, Page 2713-2728, October 2026.
ABSTRACT Chinese hamster ovary (CHO) cells are the leading host for recombinant therapeutic protein production in the biopharma industry. In this study, we investigated how feeding acidic forms of tricarboxylic acid (TCA) cycle intermediates—malic acid, succinic acid, and α‐ketoglutaric acid—affects cell culture performance and metabolism in two ...

Effects of Maternal Nutrient Restriction, IUGR, and Glucocorticoid Exposure on Phosphoenolpyruvate Carboxykinase-1 Expression in Fetal Baboon Hepatocytes In Vitro

Journal of medical primatology, 2013
The objective of this study was to develop a cell culture system for fetal baboon hepatocytes and to test the hypotheses that (i) expression of the gluconeogenic enzyme phosphoenolpyruvate carboxykinase‐1 (PEPCK‐1) is upregulated in hepatocytes isolated ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
