2,3-dihydroxybenzoate-AMP ligase.

Chorismate mutase.

Anthranilate synthase, amidotransferase component / Para-aminobenzoate synthase, amidotransferase component.

2,3-dihydro-2,3-dihydroxybenzoate dehydrogenase [enterobactin] siderophore.

Chorismate mutase I / Prephenate dehydratase.

Chorismate synthase; Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.

Anthranilate synthase, aminase component; 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 c [...]

Shikimate 5-dehydrogenase I alpha; Involved in the biosynthesis of the chorismate, which leads to the biosynthesis of aromatic amino acids. Catalyzes the reversible NADPH linked reduction of 3-dehydroshikimate (DHSA) to yield shikimate (SA).

3-dehydroquinate dehydratase II; Catalyzes a trans-dehydration via an enolate intermediate. Belongs to the type-II 3-dehydroquinase family.
