A universal metabolite repair enzyme removes a strong inhibitor of the TCA cycle

Nature Communications
A prevalent side-reaction of succinate dehydrogenase oxidizes malate to enol-oxaloacetate (OAA), a metabolically inactive form of OAA that is a strong inhibitor of succinate dehydrogenase. We purified from cow heart mitochondria an enzyme (OAT1) with OAA

Insight into the Carboxyl Transferase Domain Mechanism of Pyruvate Carboxylase from \u3cem\u3eRhizobium etli\u3c/em\u3e [PDF]

, 2009
The effects of mutations in the active site of the carboxyl transferase domain of Rhizobium etli pyruvate carboxylase have been determined for the forward reaction to form oxaloacetate, the reverse reaction to form MgATP, the oxamate-induced ...

Multistationary and Oscillatory Modes of Free Radicals Generation by the Mitochondrial Respiratory Chain Revealed by a Bifurcation Analysis [PDF]

, 2012
The mitochondrial electron transport chain transforms energy satisfying cellular demand and generates reactive oxygen species (ROS) that act as metabolic signals or destructive factors.

Rhizosphere microbial detoxification and phosphorus solubilization drive ecological remediation of Pb–Zn contaminated soils

PLANTS, PEOPLE, PLANET, EarlyView.
Heavy metal contamination of soils poses a serious threat to ecosystem health and food security worldwide. This study investigated how native plants, such as Artemisia annua and Buddleja davidii, interact with soil microbes in Pb–Zn waste slag areas. We found that these plants stimulate microbes, which improve phosphorus availability and reduce metal ...

Revealing the Diverse Allergenic Protein Repertoire of Six Widely Consumed Crab Species: A Species‐Specific Allergen in King Crab

Allergy, EarlyView.
This study comprehended the allergen profiles of six edible crab species using proteomic and transcriptomic analyses and identified 11 putative allergens. King crab has a distinct protein and allergen profile, with the discovery of malate dehydrogenase as a novel king crab‐specific allergen registered as Para c 11.

Mitochondrial Outer Membrane Permeability Change and Hypersensitivity to Digitonin Early in Staurosporine-induced Apoptosis [PDF]

, 2003
We have shown here that the apoptosis inducer staurosporine causes an early decrease in the endogenous respiration rate in intact 143B.TK- cells. On the other hand, the activity of cytochrome c oxidase is unchanged for the first 8 h after staurosporine ...

BCKDH: the missing link in apicomplexan mitochondrial metabolism is required for full virulence of Toxoplasma gondii and Plasmodium berghei [PDF]

, 2014
While the apicomplexan parasites Plasmodium falciparum and Toxoplasma gondii are thought to primarily depend on glycolysis for ATP synthesis, recent studies have shown that they can fully catabolize glucose in a canonical TCA cycle.

Protective Role for Itaconate During Inhaled Allergen Challenge

Allergy, EarlyView.
Itaconate levels decrease in sputum following allergen inhalation in mild asthmatics, suggesting a dynamic metabolic response to airway challenge. Genetic deletion of Acod1 in mice did not alter airway inflammation or remodelling in response to chronic HDM exposure.

New Allergens Approved by the WHO/IUIS Allergen Nomenclature Sub‐Committee in 2021–2024 and Their Significance for Future Diagnostics, Regulation, and Research. An EAACI Task Force Report

Allergy, EarlyView.
ABSTRACT The WHO/IUIS Allergen Nomenclature Sub‐Committee is an international body of experts that maintains the systematic nomenclature of allergenic proteins by assigning official names to newly identified allergens submitted by researchers. Here, we summarize the data on new allergens approved between 2021 and 2024.
