Function
function
Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
Catalytic activity
- 5-phospho-beta-D-ribosylamine + L-glutamate + diphosphate = 5-phospho-alpha-D-ribose 1-diphosphate + L-glutamine + H2O
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 Mg2+ ion per subunit.
Note: Binds 1 [4Fe-4S] cluster per subunit.
Pathway
Purine metabolism; IMP biosynthesis via de novo pathway; N1-(5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-diphosphate: step 1/2.
