  • GO:0005951 A protein complex that catalyzes the formation of carbamoyl phosphate; comprises a small subunit that binds and cleaves glutamine, and a large subunit that accepts the ammonia group cleaved from glutamine, binds all of the remaining substrates and effectors, and carries out all of the other catalytic events.
  • GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
  • GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
  • GO:0004088 Catalysis of the reaction: hydrogencarbonate + L-glutamine + 2 ATP + H2O = carbamoyl phosphate + L-glutamate + 2 ADP + phosphate + 2 H+.
  • GO:0004359 Catalysis of the reaction: L-glutamine + H2O = L-glutamate + NH4+.
  • GO:0006207 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:0044205 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:0071230 Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an amino acid stimulus. An amino acid is a carboxylic acids containing one or more amino groups.
  • GO:0006541 The chemical reactions and pathways involving glutamine, 2-amino-4-carbamoylbutanoic acid.
  • GO:0006526 The chemical reactions and pathways resulting in the formation of arginine, 2-amino-5-(carbamimidamido)pentanoic acid.

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

71 records

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
