| stearyl-CoA | Stearyl-coenzyme A The coenzyme A thioester of stearic acid; precursor to oleic acid and, in the brain, the C22 and C24 fatty acids present in sphingomyelins; in the brain, use of stearyl-CoA increases during myelination. (05 Mar 2000) |
| stearyl-CoA desaturase | A protein complex that is key in the synthesis of unsaturated fatty acids; it introduces a double bond at d9; high dietary levels of unsaturated fatty acids decrease this enzyme's activity in the liver; a number of agents will induce this enzyme (e.g., insulin, hydrocortisone, and triiodothyronine). (05 Mar 2000) |
| succinate-CoA ligases | <enzyme> Enzymes that catalyze the first step leading to the oxidation of succinic acid by the reversible formation of succinyl-CoA from succinate and CoA with the concomitant cleavage of ATP to ADP (ec 6.2.1.5) or GTP to GDP (ec 6.2.1.4) and orthophosphate. Itaconate can act instead of succinate and itp instead of GTP.ec 6.2.1.-. Chemical name: Succinate:CoA ligase (GDP- or ADP-forming) Registry number: EC 6.2.1.- (12 Dec 1998) |
| succinyl CoA | An intermediate product in the tricarboxylic acid cycle. (18 Nov 1997) |

| succinyl-CoA hydrolase | <enzyme> Enzyme from trichosporon cutaneum; acts on succinyl-CoA and methylsuccinyl CoA to give free acids Registry number: EC 3.1.2.3 Synonym: methylsuccinyl-CoA hydrolase, succinyl-coenzyme a hydrolase (26 Jun 1999) |
| succinyl-CoA synthetase | A ligase reversibly reacting succinate and CoA with ATP to produce ADP, inorganic phosphate, and succinyl-CoA, a similar synthetase, but one able to use itaconate as well as succinate and GTP (or ITP) in place of ATP; a part of the tricarboxylic acid cycle. Synonym: succinic thiokinase, succinyl-CoA ligase. (05 Mar 2000) |
