Reaction: acetyl-CoA + H2O + oxaloacetate = citrate + CoA

Other name(s): (R)-citrate synthase; Re-citrate-synthase; citrate oxaloacetate-lyase [(pro-3R)-CH2COO-→acetyl-CoA]
Systematic name: acetyl-CoA:oxaloacetate C-acetyltransferase [thioester-hydrolysing, (pro-R)-carboxymethyl-forming]
Comments: This enzyme is inactivated by oxygen and is found in some anaerobes. Its stereospecificity is opposite to that of EC 18.104.22.168, citrate (Si)-synthase.
