Identification
Name:Phosphoribulosylformimino-AICAR-P
Description:Phosphoribulosylformimino-aicar-p is a member of the chemical class known as 1-Phosphoribosyl-imidazolecarboxamides. These are organic compounds containing the imidazolecarboxamide linked to a ribose phosphate through a 1-2 bond. PRFAR is catalyzed by imidazole glycerol phosphate syntahse. Imidazole glycerol phosphate (IGP) synthase is a glutamine amidotransferase that catalyzes the formation of IGP and 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) from N(1)-[(5'-phosphoribulosyl)formimino]-5-aminoimidazole-4-car boxamide ribonucleotide (PRFAR). (PMID 10733892). 5-((5-phospho-1-deoxyribulos-1-ylamino)methylideneamino)-1-(5-phosphoribosyl)imidazole-4-carboxamide is an intermediate in the histidine biosynthesis pathway. It is a substrate for the enzyme 1-(5-phosphoribosyl)-5-[(5-phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase which catalyzes the reaction 1-(5-phosphoribosyl)-5-((5-phosphoribosylamino)methylideneamino)imidazole-4-carboxamide = 5-((5-phospho-1-deoxyribulos-1-ylamino)methylideneamino)-1-(5-phosphoribosyl)imidazole-4-carboxamide.
