IntEnz Enzyme Nomenclature
EC 2.7.1.223

Names

Accepted name:
aminoimidazole riboside kinase
Other name:
STM4066 (locus name)
Systematic name:
ATP:5-amino-1-(β-D-ribosyl)imidazole 5'-phosphotransferase

Reaction

Comments:

The enzyme, characterized from the bacterium Salmonella enterica, can phosphorylate exogeneously-provided 5-amino-1-(β-D-ribosyl)imidazole to form 5-amino-1-(5-phospho-β-D-ribosyl)imidazole (AIR), an important intermediate in the production of both purine mononucleotides and the hydroxymethyl pyrimidine moiety of thiamine.
