KEGG   ENZYME: 2.3.3.3
Entry
EC 2.3.3.3                  Enzyme                                 

Name
citrate (Re)-synthase;
(R)-citrate synthase;
Re-citrate-synthase;
citrate oxaloacetate-lyase [(pro-3R)-CH2COO-->acetyl-CoA]
Class
Transferases;
Acyltransferases;
Acyl groups converted into alkyl groups on transfer
Sysname
acetyl-CoA:oxaloacetate C-acetyltransferase [thioester-hydrolysing, (pro-R)-carboxymethyl-forming]
Reaction(IUBMB)
acetyl-CoA + H2O + oxaloacetate = citrate + CoA [RN:R00351]
Reaction(KEGG)
R00351
Substrate
acetyl-CoA [CPD:C00024];
H2O [CPD:C00001];
oxaloacetate [CPD:C00036]
Product
citrate [CPD:C00158];
CoA [CPD:C00010]
Comment
This enzyme is inactivated by oxygen and is found in some anaerobes. Its stereospecificity is opposite to that of EC 2.3.3.1, citrate (Si)-synthase.
History
EC 2.3.3.3 created 1972 as EC 4.1.3.28, transferred 2002 to EC 2.3.3.3
