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}.
