The end product of the glutaryl-CoA dehydrogenation pathway is crotonyl-CoA, which can then be converted into two molecules of acetyl-CoA (Fig. 7a). CsiD is a glutarate hydroxylase that uses oxygen, 2-KG and glutarate as the substrates, and CO2, succinate and l-2-HG are produced. LhgO...
These C4 molecules can then be fed into the gluconeogenesis and other biosynthesis pathways or be used to replenish intermediates in the TCA cycle [32,56]. This peroxisome/cytosol localised pathway has recently been demonstrated to play a predominant role in the assimilation of acetyl-CoA derived ...
Citrate synthase (CS, EC 2.3.3.1) is an essential component of the Krebs cycle27and is present in almost all known living organisms. It catalyses the condensation reaction of a four-carbon molecule, oxaloacetate, and the two-carbon acetate residue from acetyl coenzyme A, to form the six-car...

Acetyl-CoA carboxylase represents the starting enzyme and directs acetyl-CoA towards de-novo fatty acid biosynthesis and chain elongation. In E. coli, the four subunits form a very unstable complex that could be purified as two subcomplexes: 1) the biotin carboxylase-biotin carboxyl carrier protei...
inhibits the PDH complex in mitochondria. Thus pyruvate cannot be fully converted into acetyl-CoA and enter the TCA cycle. MYC activates LDH-A which converts cytosolic pyruvate into lactate. MCT-1 favors lactate extrusion out of the cytosol which favors angiogenesis. MYC increases glutamine entry ...

006 features the complete M00087 beta-oxidation module, genes belonging to the “Acetate to butyrate” and “Acetyl-CoA pathway” metabolisms and an integrated prophage of the Myoviridae family (Table 1). Table 1 Bacteria related to VFA metabolism. The table reports the phylum of belonging, ...
Both collagen and glutamine-derived proline synthesis in CAFs are epigenetically upregulated by increased pyruvate dehydrogenase-derived acetyl-CoA levels. PYCR1 is a cancer cell vulnerability and potential target for therapy; therefore, our work provides evidence that targeting PYCR1 may have the ...
In mitochondria, acetyl CoA enters the TCA cycle, generating 8 molecules of NADH. All these NADH molecules and those generated from glycolysis can be oxidized back to NAD+in complex I, called NADH/coenzyme Q reductase, of the electron transport chain (ETC). Ultimately, 30 molecules of ATP ar...
