Glutaconyl-1-CoA
Glutaconyl-CoA is an intermediate in the metabolism of lysine. It is an organic compound containing a coenzyme substructure, which classifies it as a fatty ester lipid molecule. Being a lipid makes the molecule hydrophobic, which makes it insoluble in water. The molecule has a molecular formula of C26H40N7O19P3S, and a molecular weight 879.62 grams per mole.

Lysine
Lysine (symbol Lys or K) is an α-amino acid that is a precursor to many proteins. It contains an α-amino group (which is in the protonated form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain lysyl ((CH2)4NH2), classifying it as a basic, charged (at physiological pH), aliphatic amino acid. It is encoded by the codons AAA and AAG. Like almost all other amino acids, the α-carbon is chiral and lysine may refer to either enantiomer or a racemic mixture of both. For the purpose of this article, lysine will refer to the biologically active enantiomer L-lysine, where the α-carbon is in the ''S'' configuration. The human body cannot synthesize lysine. It is essential in humans and must therefore be obtained from the diet. In organisms that synthesise lysine, two main biosynthetic pathways exist, the diaminopimelate and α-aminoadipate pathways, which employ distinct e ...

Glutaconate CoA-transferase
In enzymology, a glutaconate CoA-transferase () is an enzyme that catalyzes the chemical reaction :acetyl-CoA + (E)-glutaconate \rightleftharpoons acetate + glutaconyl-1-CoA Thus, the two substrates of this enzyme are acetyl-CoA and (E)-glutaconate, whereas its two products are acetate and glutaconyl-1-CoA. This enzyme belongs to the family of transferases, specifically the CoA-transferases. The systematic name of this enzyme class is acetyl-CoA:(E)-glutaconate CoA-transferase. This enzyme participates in styrene degradation Styrene () is an organic compound with the chemical formula C6H5CH=CH2. This derivative of benzene is a colorless oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concen ... and butanoate metabolism. References * EC 2.8.3 Enzymes of unknown structure {{2.8-enzyme-stub ...

Glutaconyl-CoA Decarboxylase
In enzymology, a glutaconyl-CoA decarboxylase () is an enzyme that catalyzes the chemical reaction :4-carboxybut-2-enoyl-CoA \rightleftharpoons but-2-enoyl-CoA + CO2 Hence, this enzyme has one substrate, 4-carboxybut-2-enoyl-CoA, and two products, but-2-enoyl-CoA and CO2. This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 4-carboxybut-2-enoyl-CoA carboxy-lyase (but-2-enoyl-CoA-forming). Other names in common use include glutaconyl coenzyme A decarboxylase, pent-2-enoyl-CoA carboxy-lyase, and 4-carboxybut-2-enoyl-CoA carboxy-lyase. This enzyme participates in benzoate degradation via coa ligation and butanoate metabolism.
