<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Part of a heterotetrameric complex that catalyzes the two-step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high concentrations of ammonia.1 Publication

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states.

This protein is involved in step 1 of the subpathway that synthesizes L-tryptophan from chorismate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Anthranilate synthase component 2 (trpG), Anthranilate synthase component 1 (trpE)
  2. Anthranilate phosphoribosyltransferase (trpD)
  3. N-(5'-phosphoribosyl)anthranilate isomerase (trpF)
  4. Indole-3-glycerol phosphate synthase (trpC)
  5. Tryptophan synthase beta chain 1 (trpB1), Tryptophan synthase alpha chain (trpA), Tryptophan synthase beta chain 2 (trpB2)
This subpathway is part of the pathway L-tryptophan biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-tryptophan from chorismate, the pathway L-tryptophan biosynthesis and in Amino-acid biosynthesis.
