Chain A   (Q4GZ95_TRYB2 | Q4GZ95)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0003883    CTP synthase activity    Catalysis of the reaction: ATP + UTP + NH3 = ADP + phosphate + CTP.
    GO:0016874    ligase activity    Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
biological process
    GO:0044210    'de novo' CTP biosynthetic process    The chemical reactions and pathways resulting in the formation of cytidine 5'-triphosphate (CTP) from simpler components.
    GO:0006241    CTP biosynthetic process    The chemical reactions and pathways resulting in the formation of CTP, cytidine 5'-triphosphate.
    GO:0006541    glutamine metabolic process    The chemical reactions and pathways involving glutamine, 2-amino-4-carbamoylbutanoic acid.
    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.
