Pyruvate kinase phosphatase [PDF]
FEBS Letters, 1981 1. Introduction Liver pyruvate kinase can be phosphorylated and simultaneously inactivated by CAMP-dependent pro- tein kinase; the inactivated enzyme can be reactivated by a multifunctional protein phosphatase (review [ 13). The inactivation of pyruvate kinase has been observed in isolated hepatocytes incubated in the presence of glucagon and in this ...

Microbial Cell, 2014 During growth on fermentable substrates, such as glucose, pyruvate, which is the end-product of glycolysis, can be used to generate acetyl-CoA in the cytosol via acetaldehyde and acetate, or in mitochondria by direct oxidative decarboxylation.

Protection from systemic pyruvate at resuscitation in newborn lambs with asphyxial cardiac arrest
Physiological Reports, 2020 Background Infants with hypoxic‐ischemic injury often require cardiopulmonary resuscitation. Mitochondrial failure to generate adenosine triphosphate (ATP) during hypoxic‐ischemic reperfusion injury contributes to cellular damage.

A Substrate-induced Biotin Binding Pocket in the Carboxyltransferase Domain of Pyruvate Carboxylase [PDF]
, 2013 Biotin-dependent enzymes catalyze carboxyl transfer reactions by efficiently coordinating multiple reactions between spatially distinct active sites. Pyruvate carboxylase (PC), a multifunctional biotin-dependent enzyme, catalyzes the bicarbonate- and ...

Elevated Tumor Lactate and Efflux in High-grade Prostate Cancer demonstrated by Hyperpolarized 13C Magnetic Resonance Spectroscopy of Prostate Tissue Slice Cultures. [PDF]
, 2020 Non-invasive assessment of the biological aggressiveness of prostate cancer (PCa) is needed for men with localized disease. Hyperpolarized (HP) 13C magnetic resonance (MR) spectroscopy is a powerful approach to image metabolism, specifically the ...

Control of intestinal stem cell function and proliferation by mitochondrial pyruvate metabolism. [PDF]
, 2017 Most differentiated cells convert glucose to pyruvate in the cytosol through glycolysis, followed by pyruvate oxidation in the mitochondria. These processes are linked by the mitochondrial pyruvate carrier (MPC), which is required for efficient ...

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]
, 2017 Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.
