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 ...

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.
