Malonyl-CoA: the regulator of fatty acid synthesis and oxidation [PDF]

Journal of Clinical Investigation, 2012
In the catabolic state with no food intake, the liver generates ketones by breaking down fatty acids. During the nocturnal fast or longer starvation periods, this protects the brain, which cannot oxidize fatty acids. In 1977, we published a study in the JCI noting the surprising realization that malonyl-CoA, the substrate of fatty acid synthesis, was ...

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Chloroflexus aurantiacus acetyl-CoA carboxylase evolves fused biotin carboxylase and biotin carboxyl carrier protein to complete carboxylation activity

mBio
Acetyl-CoA carboxylases (ACCs) convert acetyl-CoA to malonyl-CoA, a key step in fatty acid biosynthesis and autotrophic carbon fixation pathways. Three functionally distinct components, biotin carboxylase (BC), biotin carboxyl carrier protein (BCCP), and

Microbial Oxidative Stress in Food Fermentations: A Comprehensive Review

eFood, Volume 7, Issue 4, August 2026.
Oxidative stress has a dual role in food fermentations: low ROS supports adaptive signaling, whereas excessive ROS causes cellular damage and process inhibition. Managing redox state as a controllable process variable can improve fermentation robustness and final food quality.

Citrus Peel Xanthophylls Orchestrate Lipid–Glucose–Inflammation Axis Reprogramming in Cardiometabolic Syndrome: Integrative In Silico and In Vivo Evidence

Molecular Nutrition &Food Research, Volume 70, Issue 15, 17 August 2026.
Central obesity and dyslipidaemia converge to impair insulin signalling and trigger chronic inflammation, oxidative stress, and mitochondrial dysfunction. This integrated metabolic disruption drives lipid imbalance, apoptosis, and persistent hyperglycaemia, ultimately accelerating the progression of type 2 diabetes and cardiovascular disease.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, Volume 49, Issue 8, Page 5849-5865, August 2026.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

Characterization of the biosynthetic gene cluster of the polyene macrolide antibiotic reedsmycins from a marine-derived Streptomyces strain

Microbial Cell Factories, 2018
Background Polyene antibiotics are important as antifungal medicines albeit with serious side effects such as nephrotoxicity. Reedsmycin (RDM) A (1), produced by marine-derived Streptomyces youssoufiensis OUC6819, is a non-glycosylated polyene macrolide ...

Biosynthesis of fatty acids: IV. Studies with inhibitors

Journal of Lipid Research, 1963
Tetrolyl-CoA and propiolyl-CoA have been shown to be strong noncompetitive inhibitors of fatty acid synthesis. Acrylyl-CoA and isocrotonyl-CoA also inhibit, but much higher concentrations are required.
