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.
