CC -!- FUNCTION: Catalyzes the ATP- and formate-dependent formylation of 5-
CC aminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl 5'-monophosphate
CC (AICAR) to 5-formaminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl
CC 5'-monophosphate (FAICAR) in the absence of folates.
CC {ECO:0000255|HAMAP-Rule:MF_01163}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide +
CC ATP + formate = 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-
CC carboxamide + ADP + phosphate; Xref=Rhea:RHEA:24836,
CC ChEBI:CHEBI:15740, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:58467, ChEBI:CHEBI:58475, ChEBI:CHEBI:456216;
CC EC=6.3.4.23; Evidence={ECO:0000255|HAMAP-Rule:MF_01163};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC Note=Binds 1 Mg(2+) or Mn(2+) ion per subunit. {ECO:0000250};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; 5-
CC formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from 5-amino-
CC 1-(5-phospho-D-ribosyl)imidazole-4-carboxamide (formate route): step
CC 1/1. {ECO:0000255|HAMAP-Rule:MF_01163}.
CC -!- SIMILARITY: Belongs to the phosphohexose mutase family.
CC {ECO:0000255|HAMAP-Rule:MF_01163}.
