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.

KEGG: mfv:Mfer_0096 indole-3-glycerol-phosphate synthase; PFAM: Indole-3-glycerol phosphate synthase.

TIGRFAM: Anthranilate synthase, glutamine amidotransferase domain; KEGG: mfv:Mfer_0097 anthranilate synthase, component II; PFAM: Glutamine amidotransferase class-I, C-terminal.

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

Anthranilate synthase component I; 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 concentr [...]

KEGG: mth:MTH1537 adenylosuccinate lyase; TIGRFAM: Adenylosuccinate lyase; PFAM: Lyase 1, N-terminal; Adenylosuccinate lyase C-terminal metazoa/fungi; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.

KEGG: mst:Msp_0490 putative asparagine synthetase; TIGRFAM: Asparagine synthase, glutamine-hydrolyzing; PFAM: Asparagine synthase; Glutamine amidotransferase, class-II.

Phosphoribosylformylglycinamidine synthase 2; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist i [...]

Imidazole glycerol phosphate synthase subunit 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.
