Identification
Name: 5-amino-1-(5-phospho-β-D-ribosyl)imidazole
Description:5-aminoimidazole ribonucleotide (AIR), is an intermediate of purine nucleotide biosynthesis. It is also the precursor to 4-amino-2-methyl-5-hydroxymethylpyrimidine (HMP), the first product of pyrimidine biosynthesis. This reaction is mediated by the enzyme HMP-P kinase (ThiD). HMP is a precursor of thiamine phosphate (TMP), and subsequently to thiamine pyrophosphate (TPP). TPP is an essential cofactor in all living systems that plays a central role in metabolism. (PMID: 15326535 ). 5-Aminoimidazole ribonucleotide is a substrate for a number of proteins including: Scaffold attachment factor B2, Multifunctional protein ADE2, Pulmonary surfactant-associated protein B, Tumor necrosis factor receptor superfamily member 25, Pulmonary surfactant-associated protein C, Serine/threonine-protein kinase Chk1, Vinexin, Trifunctional purine biosynthetic protein adenosine-3, Antileukoproteinase 1 and Scaffold attachment factor B.
