Indole-3-glycerol phosphate synthase/phosphoribosylanthranilate isomerase (trpC); Similar to SP:P18304 PID:149042 percent identity: 42.65; identified by sequence similarity; putative; Belongs to the TrpC family.

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

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

Anthranilate synthase component II (trpG); 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 [...]

Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase (hisA1); Similar to SP:P10371 PID:41713 GB:U00096 PID:1736702 PID:1736711 percent identity: 32.64; identified by sequence similarity; putative.

Imidazole glycerol phosphate synthase, subunit H (hisH); IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF (By similarity).

Inosine monophosphate dehydrogenase isolog; Similar to PID:1002715 SP:P50100 percent identity: 27.56; identified by sequence similarity; putative.

Imidazoleglycerol-phosphate synthase, cyclase subunit (hisF); IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit (By similarity).
