Citrat lyase reaktion
Web2) The reaction involves the nucleophilic attack of the enol of acetyl-CoA onto the carbonyl carbon of oxaloacetate. 3) A serine residue hydrolyzes the thioester bond of citroyl-CoA to yield a protein ester intermediate that is subsequently hydrolyzed to citrate. 4) The final product, citrate, has two prochiral substituents. WebDec 15, 2003 · A citrate synthase activity (reverse reaction of ATP-citrate lyase) could not be detected in the purified enzyme, indicating a decisive role of ATP-citrate lyase in determining the direction of RTCA cycle. In addition, ADP or oxaloacetate in the reaction mixture inhibited the ATP-citrate lyase activity with an increase in concentration.
