Chain A   (PYRB_SULAC | Q55338)
molecular function
    GO:0016597    amino acid binding    Interacting selectively and non-covalently with an amino acid, organic acids containing one or more amino substituents.
    GO:0004070    aspartate carbamoyltransferase activity    Catalysis of the reaction: L-aspartate + carbamoyl phosphate = N-carbamoyl-L-aspartate + H(+) + phosphate.
    GO:0016743    carboxyl- or carbamoyltransferase activity    Catalysis of the transfer of a carboxyl- or carbamoyl group from one compound (donor) to another (acceptor).
    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.
biological process
    GO:0044205    'de novo' UMP biosynthetic process    The chemical reactions and pathways resulting in the formation of UMP, uridine monophosphate, starting with the synthesis of (S)-dihydroorotate from bicarbonate; UMP biosynthesis may either occur via reduction by quinone, NAD(+) or oxygen.
    GO:0006207    'de novo' pyrimidine nucleobase biosynthetic process    The chemical reactions and pathways resulting in the formation of pyrimidine nucleobases, 1,3-diazine, organic nitrogenous bases, beginning with the synthesis of a pyrimidine ring from simpler precursors.
    GO:0006520    cellular amino acid metabolic process    The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups, as carried out by individual cells.
    GO:0006221    pyrimidine nucleotide biosynthetic process    The chemical reactions and pathways resulting in the formation of a pyrimidine nucleotide, a compound consisting of nucleoside (a pyrimidine base linked to a deoxyribose or ribose sugar) esterified with a phosphate group at either the 3' or 5'-hydroxyl group of the sugar.

molecular function
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.

cellular component
    GO:0009347    aspartate carbamoyltransferase complex    A multienzyme complex that catalyzes the formation N-carbamoyl-L-aspartate from carbamoyl phosphate and L-aspartate. It exhibits a variety of architectural organizations, but in all microorganisms the core catalytic component is a homotrimer of approximately 34 kDa polypeptides.
