Your Input: | |||||
trpF | Pfam:pfam00697 N-(5'phosphoribosyl)anthranilate (PRA) isomerase; Belongs to the TrpF family. (209 aa) | ||||
AMM30901.1 | Anthranilate synthase; Pfam:pfam00117 Glutamine amidotransferase class-I. (213 aa) | ||||
hisC | Pfam:pfam00155 Aminotransferase class I and II; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily. (373 aa) | ||||
hisB | Pfam:pfam00475 Imidazoleglycerol-phosphate dehydratase. (210 aa) | ||||
hisH | 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. (252 aa) | ||||
hisA | Phosphoribosyl isomerase; Pfam:pfam00977 Histidine biosynthesis protein. (246 aa) | ||||
hisD | Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine. (460 aa) | ||||
hisE | Pfam:pfam01503 Phosphoribosyl-ATP pyrophosphohydrolase. (87 aa) | ||||
hisG | ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Long subfamily. (281 aa) | ||||
hisF | Imidazole glycerol phosphate synthase; 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. (257 aa) | ||||
hisI | phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP. (131 aa) | ||||
trpE | Anthranilate synthase subunit 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 concentrat [...] (532 aa) | ||||
trpC | Pfam:pfam00218 Indole-3-glycerol phosphate synthase; Belongs to the TrpC family. (280 aa) | ||||
trpB | Tryptophan synthase subunit beta; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine. (471 aa) | ||||
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. (268 aa) | ||||
trpD | Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA). (344 aa) | ||||
AMM34041.1 | Anthranilate synthase; Pfam:pfam00425 chorismate binding enzyme. (390 aa) |
