>cd06108 Ec2MCS_like Escherichia coli (Ec) 2-methylcitrate synthase (2MCS)_like. 2MCS catalyzes the condensation of propionyl-coenzyme A (PrCoA) and oxalacetate (OAA) to form 2-methylcitrate and coenzyme A (CoA) during propionate metabolism. Citrate synthase (CS) catalyzes the condensation of acetyl coenzyme A (AcCoA) and OAA to form citrate and coenzyme A (CoA), the first step in the citric acid cycle (TCA or Krebs cycle). This group contains proteins similar to the E. coli 2MCS, EcPrpC. EcPrpC is one of two CS isozymes in the gram-negative E. coli. EcPrpC is a dimeric (type I ) CS; it is induced during growth on propionate and prefers PrCoA as a substrate though it has partial CS activity with AcCoA. This group also includes Salmonella typhimurium PrpC and Ralstonia eutropha (Re) 2-MCS1 which are also induced during growth on propionate and prefer PrCoA as substrate, but can also use AcCoA. Re 2-MCS1 can use butyryl-CoA and valeryl-CoA at a lower rate. A second Ralstonia eutropha 2MC
