Engineered bacterial lipoate protein ligase A (lplA) restores lipoylation in cell models of lipoylation deficiency. [PDF]
Protein lipoylation, a vital lysine post-translational modification, plays a crucial role in the function of key mitochondrial tricarboxylic acid cycle enzymatic complexes. In eukaryotes, lipoyl post-translational modification synthesis occurs exclusively through de novo pathways, relying on lipoyl synthesis/transfer enzymes, dependent upon ...

Lipoic Acid Metabolism as a Potential Chemotherapeutic Target Against Plasmodium falciparum and Staphylococcus aureus [PDF]
Lipoic acid (LA) is an organic compound that plays a key role in cellular metabolism. It participates in a posttranslational modification (PTM) named lipoylation, an event that is highly conserved and that occurs in multimeric metabolic enzymes of very ...

Knockout studies reveal an important role of Plasmodium lipoic acid protein ligase A1 for asexual blood stage parasite survival. [PDF]
Lipoic acid (LA) is a dithiol-containing cofactor that is essential for the function of alpha-keto acid dehydrogenase complexes. LA acts as a reversible acyl group acceptor and 'swinging arm' during acyl-coenzyme A formation.

Iron overload exaggerates renal ischemia-reperfusion injury by promoting tubular cuproptosis via interrupting function of LIAS [PDF]
Renal ischemia-reperfusion injury (RIRI), a major contributor to acute kidney injury (AKI) and delayed graft function (DGF), is closely associated with dysregulation of metal ion homeostasis.

ABHD11 maintains 2-oxoglutarate metabolism by preserving functional lipoylation of the 2-oxoglutarate dehydrogenase complex [PDF]
2-oxoglutarate links mitochondrial metabolism to oxygen sensing, gene transcription and epigenetic modifications. Here, the authors describe a mutagenesis screen to find genes that control 2-oxoglutarate levels, and identify ABHD11 as a mitochondrial ...

Fruit-specific overexpression of lipoyl synthase increases both bound and unbound lipoic acid and alters the metabolome of tomato fruits [PDF]
IntroductionLipoic acid (LA) is a key, yet overlooked player in primary metabolism, due to its role as a cofactor for various multi enzymatic complexes such as the E2 subunits of pyruvate dehydrogenase (PDH) and alpha-ketoglutarate dehydrogenase (kGDH ...

CoA‐dependent activation of mitochondrial acyl carrier protein links four neurodegenerative diseases [PDF]
PKAN, CoPAN, MePAN, and PDH‐E2 deficiency share key phenotypic features but harbor defects in distinct metabolic processes. Selective damage to the globus pallidus occurs in these genetic neurodegenerative diseases, which arise from defects in CoA ...
