WebCitrate synthase (CS) catalyzes the first reaction of the TCA cycle and is generally assumed to be the rate-limiting enzyme of the cycle [3]. Increasing evidence suggests that CS activity is closely associated with various kinds of cancers. The activity of citrate synthase was measured using tissue extract prepared from Web3. Citrate synthase is an essential enzyme in the citric acid cycle; it is responsible for catalyzing the reaction that results in the formation of citrate from acetyl CoA and oxaloacetate. During this reaction, energy is produced in the form of NADH, which can subsequently be put to use in a number of different cellular functions.
