CC -!- FUNCTION: Catalyzes the formation of phosphoribosylamine from
CC phosphoribosylpyrophosphate (PRPP) and glutamine. {ECO:0000255|HAMAP-
CC Rule:MF_01931}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-phospho-beta-D-ribosylamine + diphosphate + L-glutamate = 5-
CC phospho-alpha-D-ribose 1-diphosphate + H2O + L-glutamine;
CC Xref=Rhea:RHEA:14905, ChEBI:CHEBI:15377, ChEBI:CHEBI:29985,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:58017, ChEBI:CHEBI:58359,
CC ChEBI:CHEBI:58681; EC=2.4.2.14; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01931};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01931};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01931};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; N(1)-
CC (5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-
CC diphosphate: step 1/2. {ECO:0000255|HAMAP-Rule:MF_01931}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the purine/pyrimidine
CC phosphoribosyltransferase family. {ECO:0000255|HAMAP-Rule:MF_01931}.
