Hybrid sensor histidine kinase/response regulator; At low cell density, in the absence of AI-1 (autoinducer 1), LuxN has a kinase activity and autophosphorylates on His-471. The phosphoryl group is then transferred on Asp-771 of the response regulator domain. The phosphoryl group is transferred to LuxU, and ultimately to LuxO. At high cell density, in the presence of AI-1, the kinase activity is inactivated, and the response regulator domain has a phosphatase activity. LuxN phosphatase acts on itself. As LuxU could function to establish an equilibrium between the aspartyl-phosphate of [...]

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

Tryptophan synthase subunit beta; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.

Homoserine/homoserine lactone efflux protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

Acyl-homoserine-lactone synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Bifunctional indole-3-glycerol phosphate synthase/phosphoribosylanthranilate isomerase; Monomeric bifunctional protein; functions in tryptophan biosynthesis pathway; phosphoribosylanthranilate is rearranged to carboxyphenylaminodeoxyribulosephosphate which is then closed to form indole-3-glycerol phosphate; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the TrpC family.

Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).

Cation acetate symporter; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the sodium:solute symporter (SSF) (TC 2.A.21) family.
