Cell 59:22-34(2015). CC -!- FUNCTION: Peroxisomal citrate synthase involved in the citrate CC homeostasis (PubMed:3023912, PubMed:25982115). Catalyzes the CC condensation of acetyl coenzyme A and oxaloacetate to form citrate CC (PubMed:3023912, PubMed:25982115). Citrate synthase is the rate- CC limiting enzyme of the tricarboxylic acid (TCA) cycle (Probable). CC {ECO:0000269|PubMed:25982115, ECO:0000269|PubMed:3023912, CC ECO:0000305|PubMed:3023912}. CC -!- CATALYTIC ACTIVITY: CC Reaction=acetyl-CoA + H2O + oxaloacetate = citrate + CoA + H(+); CC Xref=Rhea:RHEA:16845, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:16452, ChEBI:CHEBI:16947, ChEBI:CHEBI:57287, CC ChEBI:CHEBI:57288; EC=2.3.3.16; Evidence={ECO:0000255|PROSITE- CC ProRule:PRU10117, ECO:0000269|PubMed:3023912}; CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; isocitrate CC from oxaloacetate: step 1/2. {ECO:0000269|PubMed:3023912}. CC -!- SUBUNIT: Interacts with F-box protein UCC1. CC {ECO:0000269|PubMed:25982115}. CC -!- INTERACTION: CC P08679; P08679: CIT2; NbExp=3; IntAct=EBI-4713, EBI-4713; CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:25982115}. CC Peroxisome {ECO:0000269|PubMed:2181273, ECO:0000269|PubMed:25982115}. CC -!- INDUCTION: Expression is repressed in medium containing both glucose CC and glutamate (PubMed:3023912). Expression is up-regulated by the CC presence of C2-compounds such as acetate (PubMed:25982115). CC {ECO:0000269|PubMed:25982115, ECO:0000269|PubMed:3023912}. CC -!- PTM: Ubiquitinated by the E3 ubiquitin-protein ligase complex CC SCF(UCC1), which leads to its degradation by the proteasome CC (PubMed:25982115). Ubiquitination is prevented by oxaloacetate, CC suggesting the existence of an oxaloacetate-dependent positive feedback CC loop that stabilizes CIT2 (PubMed:25982115). CC {ECO:0000269|PubMed:25982115}. CC -!- DISRUPTION PHENOTYPE: Leads to glutamate auxotrophy and poor growth on CC rich medium containing lactate, a nonfermentable carbon source, when CC CIT1 is also deleted. {ECO:0000269|PubMed:3023912}. CC -!- MISCELLANEOUS: Citrate synthase is found in nearly all cells capable of CC oxidative metabolism. {ECO:0000305}. CC -!- MISCELLANEOUS: Present with 2310 molecules/cell in log phase SD medium. CC {ECO:0000269|PubMed:14562106}. CC -!- SIMILARITY: Belongs to the citrate synthase family. {ECO:0000305}.
