Citrat lyase reaktion
WebJun 18, 2024 · In the cytoplasm, citrate is converted to oxaloacetate and acetyl-CoA by the ATP-driven ATP-citrate lyase (ACL) reaction. This reaction is essentially the reverse of that catalyzed by the TCA enzyme citrate synthase except it requires the energy of ATP hydrolysis to drive it forward. The resultant oxaloacetate is converted to malate by malate ... Websome can be formed from the oxidation of oxaloacetate, which is generated by ATP-citrate lyase. it can also be generated by the combined action of cytoplasmic malate dehydrogenase and magic enzyme. it can be provided by the pentose phosphate pathway. ... the product of the reaction catalyzed by acetyl COA carboxylase, malonyl CoA, …

WebLyases are a group of enzymes (EC 4) that catalyze the breakdown of chemical bonds through methods other than hydrolysis or oxidation. They differ from other enzyme classes in that most reactions catalyzed by lyases only require one substrate molecule for the forward reaction, and two for the reverse reaction. Lyases are further categorized ... WebJan 1, 1972 · Citrate lyase has been reported only in certain bacteria, citrate synthase has been found in all cells examined for it, and ATP citrate lyase has been found only in eukaryotic cells. The reaction catalyzed in common by these three enzymes is an aldol type, that is the reversible formation of a C—H bond from a C—C bond.
