Enzyme Information
6.3.4.23 |
Formate--phosphoribosylaminoimidazolecarboxamide ligase.
based on mapping to UniProt Q8U0R7
ATP + formate + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide = ADP + phosphate + 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4- carboxamide.
-!- This archaeal enzyme, characterized from the methanogen Methanocaldococcus jannaschii, catalyzes a step in the synthesis of purine nucleotides. -!- It differs from the orthologous bacterial/eukaryotic enzymes, which utilize 10-formyltetrahydrofolate rather than formate and ATP. -!- Cf. EC 2.1.2.3.
