Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

Angewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Acetate Recapturing by Nuclear Acetyl-CoA Synthetase 2 Prevents Loss of Histone Acetylation during Oxygen and Serum Limitation

Cell Reports, 2017
Acetyl-CoA is a key metabolic intermediate with an important role in transcriptional regulation. The nuclear-cytosolic acetyl-CoA synthetase 2 (ACSS2) was found to sustain the growth of hypoxic tumor cells.

Glucose and Glutamine Deprivation Promotes Breast Cancer Lung Metastasis via BRD4‐Dependent Enhancer Activation

Advanced Science, EarlyView.
To model a nutrient‐restricted tumor microenvironment, breast cancer cells were adapted to low glucose and glutamine levels. In the adapted cells, BRD4‐driven enhancer activation increases pro‐invasive EDN1 expression, facilitated by ATF3/c‐JUN and reinforced by enhancer RNA.

A Conserved Isoleucine Gates the Diffusion of CO and O2 to the Active Site of NiFe CO‐Dehydrogenase

Angewandte Chemie, EarlyView.
A combination of protein film electrochemistry and site‐directed mutagenesis shows that isoleucine 563 (numbering of Thermococcus sp. AM4) gates the arrival of both CO and O2 to the active site of the nickel‐iron CO dehydrogenases. Mutations at this position increase the resistance to O2 at the cost of a slower reaction with CO.

Acetyl-L-carnitine flux to lipids in cells estimated using isotopomer spectral analysis

Journal of Lipid Research, 1997
Acetyl-L-carnitine is known as a reservoir of activated acetyl units and as a modulator of metabolic function. The objective of this study was to quantify the fate of the acetyl moiety of acetyl-L-carnitine in lipogenic pathways.

Replacement of the Saccharomyces cerevisiae acetyl-CoA synthetases by alternative pathways for cytosolic acetyl-CoA synthesis

, 2013
Cytosolic acetyl-coenzyme A is a precursor for many biotechnologically relevant compounds produced by Saccharomyces cerevisiae. In this yeast, cytosolic acetyl-CoA synthesis and growth strictly depend on expression of either the Acs1 or Acs2 isoenzyme of

The Distinctive Regulatory Mechanisms of Bacterial Acetyl-CoA Carboxylase [PDF]

, 2018
Metabolic Regulation is a complex system used to control cellular metabolism in response to conditions in the cell’s environment. For most enzymes, the cell can rely upon a minimal amount of regulation; however, critical enzymes, such as acetyl-CoA ...

Targeting the KAT7/H3K14ac/RAC2 Axis Mediates OXPHOS to Promote Stemness Maintenance and Malignancy in Glioblastoma

Advanced Science, EarlyView.
SOX2 upregulates KAT7 in glioma stem cells, where KAT7 deposits H3K14 acetylation at the RAC2 promoter to activate RAC2 transcription. RAC2‐GTP subsequently promotes PAK1/2/3 phosphorylation, increasing tricarboxylic acid cycle flux and mitochondrial respiration to support glioblastoma malignancy.

Lyssavirus Nucleoprotein Induces GPAT4‐Mediated CYB5R1 Depalmitoylation to Suppress Ferroptosis and Promote Viral Replication

Advanced Science, EarlyView.
Lipid metabolism plays a vital role in viral infections. Here, we reveal that the lyssavirus N protein regulates GPAT4 to induce lipid droplet biogenesis, restricting CYB5R1 palmitoylation and reducing ferroptosis susceptibility to ultimately promote viral replication.

Acetylation dynamics and stoichiometry in Saccharomyces cerevisiae

Molecular Systems Biology, 2014
Lysine acetylation is a frequently occurring posttranslational modification; however, little is known about the origin and regulation of most sites.
