General annotation (Comments)

Catalytic activity	5-phospho-beta-D-ribosylamine + diphosphate + L-glutamate = L-glutamine + 5-phospho-alpha-D-ribose 1-diphosphate + H2O.
Cofactor	Binds 1 magnesium ion per subunit By similarity. Binds 1 4Fe-4S cluster per subunit By similarity.
Enzyme regulation	Activated by the substrate 5-phospho-alpha-D-ribosyl-1-pyrophosphate and inhibited by the purine ribonucleotides, the end products of purine biosynthesis.
Pathway	Purine metabolism; IMP biosynthesis via de novo pathway; N(1)-(5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-diphosphate: step 1/2.
Subunit structure	Homotetramer.
Tissue specificity	Expressed at a high level in brain, heart, liver and stomach.
Sequence similarities	In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family. Contains 1 glutamine amidotransferase type-2 domain.
