WebCitrate, a Krebs cycle (i.e., TCA cycle or citric acid cycle) intermediate, is generated by many bacteria; however, utilization of exogenous citrate requires the presence of citrate transport proteins (permeases) (7). Upon uptake by the cell, citrate is cleaved by citrate lyase to oxaloacetate and acetate. The oxaloacetate is then metabolized to 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.
