HHsearch alignment for GI: 254781020 and conserved domain: TIGR00735

>TIGR00735 hisF imidazoleglycerol phosphate synthase, cyclase subunit; InterPro: IPR004651 Histidine is formed by several complex and distinct biochemical reactions catalysed by eight enzymes. Proteins involved in steps 4 and 6 of the histidine biosynthesis pathway are contained in one family. These enzymes are called His6 and His7 in eukaryotes and HisA and HisF in prokaryotes. HisA is a phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase (), involved in the fourth step of histidine biosynthesis. The bacterial HisF protein is a cyclase which catalyzes the cyclization reaction that produces D-erythro-imidazole glycerol phosphate during the sixth step of histidine biosynthesis. The yeast His7 protein is a bifunctional protein which catalyzes an amido-transferase reaction that generates imidazole-glycerol phosphate and 5-aminoimidazol-4-carboxamide. The latter is the ribonucleotide used for purine biosynthesis. The enzyme also catalyzes the cyclization reaction that produces D-erythro-imidazole glycerol phosphate, and is involved in the fifth and sixth steps in histidine biosynthesis. This family describes the histidine biosynthesis protein, HisF. ; GO: 0000107 imidazoleglycerol-phosphate synthase activity, 0000105 histidine biosynthetic process, 0005737 cytoplasm, 0009382 imidazoleglycerol-phosphate synthase complex.
