  IntEnz view ENZYME view

IntEnz Enzyme Nomenclature


Accepted name:
ATP citrate synthase
Other names:
ATP citrate (pro-S)-lyase
ATP-citric lyase
ATP:citrate oxaloacetate-lyase [(pro-S)-CH2COO→acetyl-CoA] (ATP-dephosphorylating)
acetyl-CoA:oxaloacetate acetyltransferase (isomerizing; ADP-phosphorylating)
adenosine triphosphate citrate lyase
citrate cleavage enzyme
citrate-ATP lyase
citric cleavage enzyme
Systematic name:
acetyl-CoA:oxaloacetate C-acetyltransferase [(pro-S)-carboxymethyl-forming, ADP-phosphorylating]



The enzyme can be dissociated into components, two of which are identical with EC (citryl-CoA lyase) and EC (citrate—CoA ligase).
