Application

Acetyl-CoA is an essential cofactor and carrier of acyl groups in enzymatic acetyl transfer reactions. Acetyl CoA is formed either by the oxidative decarboxylation of pyruvate in mitochondria, by the oxidation of long-chain fatty acids, or by the oxidative degradation of certain amino acids. Acetyl-CoA is the starting compound for the citric acid cycle (Krebs cycle). Acetyl CoA is also a key precursor in lipid biosynthesis, and the source of all fatty acid carbons. Acetyl-CoA positively regulates the activity pyruvate carboxylase. Acetyl CoA is a precursor of the neurotransmitter acetylcholine. Histone acetylases (HAT) use Acetyl-CoA as the donor for the acetyl group use in the post-translational acetylation reactions of histone and non-histone proteins.

Histone posttranslational modifications and chromatin dynamics are inextricably linked to eukaryotic gene expression. Among the many modifications that have been characterized, histone tail acetylation is most strongly correlated with transcriptional activation.

Lysine (K) acetylation refers to transfer of the acetyl moiety from acetyl-CoA to the ε-amino group of a lysine residue. This is posttranslational and reversible, with its level dynamically maintained by lysine acetyltransferases (KATs) and deacetylases (KDACs). Traditionally, eukaryotic KDACs

Glutamine Metabolism is Dysregulated in Many Cancer Cells

This is an article about how proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity.

Fatty Acid Synthesis and Metabolism in Cancer Cells

Information on fatty acid synthesis and metabolism in cancer cells. Learn how proliferatively active cells require fatty acids for functions such as membrane generation, protein modification, and bioenergetic requirements. These fatty acids are derived either from dietary sources or are synthesized by the cell.
