GO:0004049 Catalysis of the reaction: chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate. GO:0046872 Binding to a metal ion. GO:0000162 The chemical reactions and pathways resulting in the formation of L-tryptophan, the chiral amino acid 2-amino-3-(1H-indol-3-yl)propanoic acid; L-tryptophan is synthesized from chorismate via anthranilate. GO:0009058 A cellular process consisting of the biochemical pathways by which a living organism synthesizes chemical substances. This typically represents the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.

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.

54 records

Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.

No PDB structure with a co-crystallized ligand found for this exact protein.

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.
