Para-aminobenzoate synthase glutamine amidotransferase component II.

TrpA Tryptophan synthase alpha chain; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.

Indole-3-glycerol phosphate synthase; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine; Belongs to the TrpC family.

hisA 1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase.

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.

pheA Prephenate dehydratase.

3-dehydroquinate synthase; Catalyzes the conversion of 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) to dehydroquinate (DHQ); Belongs to the sugar phosphate cyclases superfamily. Dehydroquinate synthase family.

Aspartate-semialdehyde dehydrogenase; Belongs to the aspartate-semialdehyde dehydrogenase family.

Protein translocase subunit secA; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
