IUBMB Enzyme Nomenclature


Accepted name: citrate (pro-3S)-lyase

Reaction: citrate = acetate + oxaloacetate

Other name(s): citrase; citratase; citritase; citridesmolase; citrate aldolase; citric aldolase; citrate lyase; citrate oxaloacetate-lyase; citrate oxaloacetate-lyase [(pro-3S)-CH2COO-→acetate]

Systematic name: citrate oxaloacetate-lyase (forming acetate from the pro-S carboxymethyl group of citrate)

Comments: The enzyme can be dissociated into components, two of which are identical with EC (citrate CoA-transferase) and EC (citryl-CoA lyase). EC (citrate lyase deacetylase) thiolesterase, deacetylates and inactivates the enzyme.
