CC -!- FUNCTION: Component of the methylcitrate cycle that catalyzes the
CC synthesis of (2S,3S)-2-methylcitrate from propionyl-CoA and
CC oxaloacetate. Plays an important role in detoxification of propionyl-
CC CoA, an inhibitor of both primary and secondary metabolism. Has also
CC citrate synthase activity using as substrates acetyl-CoA and
CC oxaloacetate. {ECO:0000269|PubMed:19661181}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + oxaloacetate + propanoyl-CoA = (2S,3S)-2-methylcitrate +
CC CoA + H(+); Xref=Rhea:RHEA:23780, ChEBI:CHEBI:15377,

CC Evidence={ECO:0000269|PubMed:19661181};
CC -!- CATALYTIC ACTIVITY:

CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=1.88 uM for propionyl-CoA {ECO:0000269|PubMed:19661181};
CC KM=2.71 uM for acetyl-CoA {ECO:0000269|PubMed:19661181};
CC KM=2.81 uM for oxaloacetate (in presence of propionyl-CoA)
CC {ECO:0000269|PubMed:19661181};
CC KM=9.64 uM for propionyl-CoA (in presence of acetyl-CoA)
CC {ECO:0000269|PubMed:19661181};
CC pH dependence:
CC Optimum pH is 8.0-9.0. {ECO:0000269|PubMed:19661181};
CC Temperature dependence:
CC Optimum temperature is 49-54 degrees Celsius.
CC {ECO:0000269|PubMed:19661181};
CC -!- PATHWAY: Organic acid metabolism; propanoate degradation.
CC {ECO:0000305}.
CC -!- SUBUNIT: Homodimer. {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the citrate synthase family. {ECO:0000305}.
