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...
Small molecules have consistently enabled medical breakthroughs and tackling unmet medical needs, thus saving countless lives. Moreover, small molecules have been vital as chemical probes in biomedical research, aiding understanding of disease biology. Traditional small-molecule drugs have been the dominant...
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...

[145,146]. LDHA phosphorylation provides invasive signals in metastatic cancer cells by regulating redox status, and LDHA can also enhance tumor progression by possessing molecules related to EMT [147]. When LDHA is inhibited, more pyruvate will enter the tricarboxylic acid (TCA) cycle, resulting ...
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 ...
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 ...
Functional composition from the KEGG comparative analysis showed that long-chain fatty acids were degraded to acetyl-CoA or converted into aldehydes and alcohols in the fatty acid degradation pathway (ko00071). Acetyl-CoA then acted to facilitate the fatty acid biosynthesis pathway (ko00061), ...
