Citrate synthase (E.C. 2.3.3.1 (previously 4.1.3.7)) is an enzyme that exists in nearly all living cells. It functions as a pace-making enzyme in the first step of the citric acid cycle (or Krebs cycle). [5] Citrate synthase is located within eukaryotic cells in the mitochondrial matrix, but is encoded by nuclear DNA rather than
In molecular biology, the citrate synthase family of proteins includes the enzymes citrate synthase EC 2.3.3.1, and the related enzymes 2-methylcitrate synthase EC 2.3.3.5 and ATP citrate lyase EC 2.3.3.8. Citrate synthase is a member of a small family of enzymes that can directly form a carbon-carbon bond without the presence of metal ion ...
Aldol condensation: Oxaloacetate + Acetyl CoA + H 2 O Citrate synthase: Citrate + CoA-SH: This is the same as step 0 and restarts the cycle. The reaction is irreversible and extends the 4C oxaloacetate to a 6C molecule
Oxoglutarate dehydrogenase is a key control point in the citric acid cycle. It is inhibited by its products, succinyl CoA and NADH.A high energy charge in the cell will also be inhibitive.
The aldol reaction (aldol addition) is a reaction in organic chemistry that combines two carbonyl compounds (e.g. aldehydes or ketones) to form a new β-hydroxy carbonyl compound. Its simplest form might involve the nucleophilic addition of an enolized ketone to another:
ATP citrate synthase (also ATP citrate lyase (ACLY)) is an enzyme that in animals catalyzes an important step in fatty acid biosynthesis. [2] By converting citrate to acetyl-CoA , the enzyme links carbohydrate metabolism , which yields citrate as an intermediate , with fatty acid biosynthesis , which consumes acetyl-CoA. [ 3 ]
The aldol cleavage or Retro-aldol reaction is the reverse reaction into the starting compounds. The name aldehyde -alcohol reaction derives from the reaction product in the case of a reaction among aldehydes, a β-hydroxy aldehyde .
