                    | UPA00031 | L-histidine biosynthesis~Biosynthesis of L-histidine, (S)-alpha-Amino- 1H-imidazole-4-propionic acid, a weakly basic amino-acid in a nine- step pathway. Histidine biosynthetic pathway is present in microbes, fungi and plants. Histidine biosynthesis is unusual as a metabolic process utilizing the purine ring of ATP as a carbon and nitrogen source. Histidine biosynthesis pathway is connected to de novo purine biosynthesis pathway through imidazole glycerol phosphate synthase (IGPS) which catalyzes the fifth step and converts N-(5'-phosphoribulosys)-formimino-5-aminoimidazole-4-carboxamide ribonucleotide (PRFAR) to imidazole glycerol phosphate (ImGP) and 5'-(5-aminoimidazole-4-carboxamide) ribonucleotide (AICAR). AICAR is the entry point to the purine biosynthetic pathway. | True - {{t}} | None - {{∅},{t}} | Missing |  |
