Comments
[?]
| FUNCTION | Catalyzes the ATP- and formate-dependent formylation of 5- aminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl 5'-monophosphate (AICAR) to 5-formaminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl 5'-monophosphate (FAICAR) in the absence of folates. |
| CATALYTIC ACTIVITY | Reaction=5-amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide + formate + ATP = 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4- carboxamide + ADP + phosphate; Xref=Rhea:RHEA:24836, ChEBI:CHEBI:15740, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:58467, ChEBI:CHEBI:58475, ChEBI:CHEBI:456216; EC=6.3.4.23; |
| PATHWAY | Purine metabolism; IMP biosynthesis via de novo pathway; 5- formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from 5-amino- 1-(5-phospho-D-ribosyl)imidazole-4-carboxamide (formate route): step 1/1. |
| SIMILARITY | Belongs to the phosphohexose mutase family. |
