Citrate synthase is found in nearly all cells capable of oxidative metabolism.

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> section describes the catalytic activity of an enzyme, i.e. a chemical reaction that the enzyme catalyzes.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityi

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">'Function'</a> section describes the metabolic pathway(s) associated with a protein.<p><a href='/help/pathway' target='_top'>More...</a></p>Pathwayi: tricarboxylic acid cycle

This protein is involved in step 1 of the subpathway that synthesizes isocitrate from oxaloacetate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Citrate synthase, mitochondrial (CS)
  2. Aconitate hydratase, mitochondrial (ACO2)
This subpathway is part of the pathway tricarboxylic acid cycle, which is itself part of Carbohydrate metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes isocitrate from oxaloacetate, the pathway tricarboxylic acid cycle and in Carbohydrate metabolism.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
