Chain A (PRPC_ABDS2 | O34002)

molecular function
	GO:0050440	2-methylcitrate synthase activity	Catalysis of the reaction: H(2)O + oxaloacetate + propanoyl-CoA = (2R,3S)-2-methylcitrate + CoA + H(+).
	GO:0036440	citrate synthase activity	Catalysis of the reaction: acetyl-CoA + H2O + oxaloacetate = citrate + CoA.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
	GO:0046912	transferase activity, transferring acyl groups, acyl groups converted into alkyl on transfer	Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor), with the acyl group being converted into alkyl on transfer.
biological process
	GO:0019679	propionate metabolic process, methylcitrate cycle	The chemical reactions and pathways involving propionate that occur in the methylcitrate cycle.
	GO:0006099	tricarboxylic acid cycle	A nearly universal metabolic pathway in which the acetyl group of acetyl coenzyme A is effectively oxidized to two CO2 and four pairs of electrons are transferred to coenzymes. The acetyl group combines with oxaloacetate to form citrate, which undergoes successive transformations to isocitrate, 2-oxoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate again, thus completing the cycle. In eukaryotes the tricarboxylic acid is confined to the mitochondria. See also glyoxylate cycle.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
