FDX1 regulates cellular protein lipoylation through direct binding to LIAS. [PDF]
AbstractFerredoxins are a family of iron-sulfur (Fe-S) cluster proteins that serve as essential electron donors in numerous cellular processes that are conserved through evolution. The promiscuous nature of ferredoxins as electron donors enables them to participate in many metabolic processes including steroid, heme, vitamin D and Fe-S cluster ...

Protein lipoylation in mitochondria requires Fe-S cluster assembly factors NFU4 and NFU5. [PDF]
Abstract Plants have evolutionarily conserved NifU (NFU)-domain proteins that are targeted to plastids or mitochondria. “Plastid-type” NFU1, NFU2, and NFU3 in Arabidopsis (Arabidopsis thaliana) play a role in iron–sulfur (Fe–S) cluster assembly in this organelle, whereas the type-II NFU4 and NFU5 proteins have not been subjected to ...

Glycine decarboxylase maintains mitochondrial protein lipoylation to support tumor growth. [PDF]
The folic acid cycle mediates the transfer of one-carbon (1C) units to support nucleotide biosynthesis. While the importance of serine as a mitochondrial and cytosolic donor of folate-mediated 1C units in cancer cells has been thoroughly investigated, a potential role of glycine oxidation remains unclear.

Protein lipoylation: an evolutionarily conserved metabolic regulator of health and disease. [PDF]
Lipoylation is a rare, but highly conserved lysine posttranslational modification. To date, it is known to occur on only four multimeric metabolic enzymes in mammals, yet these proteins are staples in the core metabolic landscape. The dysregulation of these mitochondrial proteins is linked to a range of human metabolic disorders.

Protein lipoylation in cancer: metabolic reprogramming and therapeutic potential. [PDF]
Abstract Protein lipoylation, a mitochondria-specific post-translational modification (PTM) evolutionarily conserved from bacteria to mammals, plays critical role in metabolic processes. In humans, four identified lipoylated proteins serve as essential components of key enzymes involved in glycolysis, the tricarboxylic acid (TCA) cycle, and ...

Mitochondrial Protein Lipoylation and the 2-Oxoglutarate Dehydrogenase Complex Controls HIF1α Stability in Aerobic Conditions. [PDF]
Hypoxia-inducible transcription factors (HIFs) control adaptation to low oxygen environments by activating genes involved in metabolism, angiogenesis, and redox homeostasis. The finding that HIFs are also regulated by small molecule metabolites highlights the need to understand the complexity of their cellular regulation.

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 ...
