6-Oxocyclohex-1-ene-1-carboxyl-CoA
6-Oxocyclohex-1-ene-1-carboxyl-CoA is involved in benzoyl-CoA degradation II path way. Benzoyl-CoA is a common intermediate in the anaerobic bacterial metabolism of many aromatic substrates. Two enzymes and ferredoxin of the central benzoyl-CoA pathway in Thauera aromatica have been purified so far. Benzoyl-CoA reductase reduces the aromatic ring with reduced ferredoxin yielding cyclohexa-1,5-diene-1-carbonyl-CoA [Boll, M. & Fuchs, G. (1995) Eur. J. Biochem. 234, 921-933]. Dienoyl-CoA hydratase subsequently adds one molecule of water and thereby produces 6-hydroxycyclohex-1-ene-1-carbonyl-CoA [Laempe, D., Eisenreich, W., Bacher, A., & Fuchs, G. (1998) Eur. J. Biochem. 255, 618-627]. 6-Hydroxycyclohex-1-ene-1-carbonyl-CoA dehydrogenase is an NAD(+)-specific beta-hydroxyacyl-CoA dehydrogenase that catalyzes 6-hydroxycyclohex-1-ene-1-carbonyl-CoA + NAD(+) --> 6-oxocyclohex-1-ene-1-carbonyl-CoA + NADH + H(+). 6-Oxocyclohex-1-ene-1-carbonyl-CoA hydrolase acts on the beta-oxoacyl-CoA compound and catalyzes the addition of one molecule of water to the double bond and the hydrolytic C-C cleavage of the alicyclic ring, 6-oxocyclohex-1-ene-1-carbonyl-CoA + 2 H(2)O --> 3-hydroxypimelyl-CoA.(PMID: 10406950) [HMDB] 6-Oxocyclohex-1-ene-1-carboxyl-CoA is involved in benzoyl-CoA degradation II path way.

octa-2,6-dienoyl-CoA
Octa-2,6-dienoyl-coa is an acyl-CoA or acyl-coenzyme A. More specifically, it is an octa-2_6-dienoic acid thioester of coenzyme A. Octa-2,6-dienoyl-coa is an acyl-CoA with 8 fatty acid group as the acyl moiety attached to coenzyme A. Coenzyme A was discovered in 1946 by Fritz Lipmann (Journal of Biological Chemistry (1946) 162 (3): 743–744) and its structure was determined in the early 1950s at the Lister Institute in London. Coenzyme A is a complex, thiol-containing molecule that is naturally synthesized from pantothenate (vitamin B5), which is found in various foods such as meat, vegetables, cereal grains, legumes, eggs, and milk. More specifically, coenzyme A (CoASH or CoA) consists of a beta-mercaptoethylamine group linked to the vitamin pantothenic acid (B5) through an amide linkage and 3-phosphorylated ADP. Coenzyme A is synthesized in a five-step process that requires four molecules of ATP, pantothenate and cysteine. It is believed that there are more than 1100 types of acyl-CoA’s in the human body, which also corresponds to the number of acylcarnitines in the human body. Acyl-CoAs exists in all living species, ranging from bacteria to plants to humans. The general role of acyl-CoA’s is to assist in transferring fatty acids from the cytoplasm to mitochondria. This process facilitates the production of fatty acids in cells, which are essential in cell membrane structure. Acyl-CoAs are also susceptible to beta oxidation, forming, ultimately, acetyl-CoA. Acetyl-CoA can enter the citric acid cycle, eventually forming several equivalents of ATP. In this way, fats are converted to ATP -- or biochemical energy. Acyl-CoAs can be classified into 9 different categories depending on the size of their acyl-group: 1) short-chain acyl-CoAs; 2) medium-chain acyl-CoAs; 3) long-chain acyl-CoAs; and 4) very long-chain acyl-CoAs; 5) hydroxy acyl-CoAs; 6) branched chain acyl-CoAs; 7) unsaturated acyl-CoAs; 8) dicarboxylic acyl-CoAs and 9) miscellaneous acyl-CoAs. Short-chain acyl-CoAs have acyl-groups with two to four carbons (C2-C4), medium-chain acyl-CoAs have acyl-groups with five to eleven carbons (C5-C11), long-chain acyl-CoAs have acyl-groups with twelve to twenty carbons (C12-C20) while very long-chain acyl-CoAs have acyl groups with more than 20 carbons. Octa-2,6-dienoyl-coa is therefore classified as a medium chain acyl-CoA. The oxidative degradation of fatty acids is a two-step process, catalyzed by acyl-CoA synthetase/synthase. Fatty acids are first converted to their acyl phosphate, the precursor to acyl-CoA. The latter conversion is mediated by acyl-CoA synthase. Three types of acyl-CoA synthases are employed, depending on the chain length of the fatty acid. Octa-2,6-dienoyl-coa, being a medium chain acyl-CoA is a substrate for medium chain acyl-CoA synthase. The second step of fatty acid degradation is beta oxidation. Beta oxidation occurs in mitochondria and, in the case of very long chain acyl-CoAs, the peroxisome. After its formation in the cytosol, octa-2,6-dienoyl-CoA is transported into the mitochondria, the locus of beta oxidation. Transport of octa-2,6-dienoyl-CoA into the mitochondria requires carnitine palmitoyltransferase 1 (CPT1), which converts octa-2,6-dienoyl-CoA into octa-2_6-dienoylcarnitine, which gets transported into the mitochondrial matrix. Once in the matrix, octa-2_6-dienoylcarnitine is converted back to octa-2,6-dienoyl-CoA by CPT2, whereupon beta-oxidation can begin. Beta oxidation of octa-2,6-dienoyl-CoA occurs in four steps. First, since octa-2,6-dienoyl-CoA is a medium chain acyl-CoA it is the substrate for a medium chain acyl-CoA dehydrogenase, which catalyzes dehydrogenation of octa-2,6-dienoyl-CoA, creating a double bond between the alpha and beta carbons. FAD is the hydrogen acceptor, yielding FADH2. Second, Enoyl-CoA hydrase catalyzes the addition of water across the newly formed double bond to make an alcohol. Third, 3-hydroxyacyl-CoA dehydrogenase oxidizes the alcohol group to a ketone and ...

Short-chain acyl-CoAs have acyl-groups with two to four carbons (C2-C4), medium-chain acyl-CoAs have acyl-groups with five to eleven carbons (C5-C11), long-chain acyl-CoAs have acyl-groups with twelve to twenty carbons (C12-C20) while very long-chain acyl-CoAs have acyl groups with more than 20 carbons.

trans-3-cis-5-octadienoyl-CoA
A medium-chain fatty acyl-CoA that results from the formal condensation of the thiol group of coenzyme A with the carboxy group of trans-3-cis-5-octadienoic acid.
6-oxocyclohex-1-ene-1-carbonyl-CoA
A 3-oxoacyl-CoA that results from the formal condensation of the thiol group of coenzyme A with the carboxy group of 6-oxocyclohex-1-ene-1-carboxylic acid.
octanoyl-CoA(4-)
An acyl-CoA(4-) that is the tetraanion of octanoyl-CoA, arising from deprotonation of phosphate and diphosphate functions.
(E)-4-(trimethylammonio)but-2-enoyl-CoA(3-)
An acyl-CoA oxoanion obtained via deprotonation of the phosphate and diphosphate OH groups of (E)-4-(trimethylammonio)but-2-enoyl-CoA; major species at pH 7.3.
3-hydroxycyclohexa-1,5-diene-1-carbonyl-CoA
An acyl-CoA that results from the formal condensation of the thiol group of coenzyme A with the carboxy group of 3-hydroxycyclohexa-1,5-diene-1-carboxylic acid.
trans,trans-octa-2,4-dienoyl-CoA
A trans,trans-2,3,4,5-tetradehydroacyl-CoA having trans,trans-octa-2,4-dienoyl as the S-acyl component.
