In enzymology, a citrate (pro-3S)-lyase (EC 4.1.3.6) is an enzyme that catalyzes the chemical reaction
- citrate acetate + oxaloacetate
Hence, this enzyme has one substrate, citrate, and two products, acetate and oxaloacetate.
This enzyme belongs to the family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is citrate oxaloacetate-lyase (forming acetate from the pro-S carboxymethyl group of citrate). Other names in common use include citrase, citratase, citritase, citridesmolase, citrate aldolase, citric aldolase, citrate lyase, citrate oxaloacetate-lyase, and citrate oxaloacetate-lyase [(pro-3S)-CH2COO-->acetate]. This enzyme participates in citrate cycle and two-component system - general.
Structural studies
As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1U5H, 1U5V, 1Z6K, and 2HJ0.
