Protein
Phosphoribosylglycinamide formyltransferase 2
Gene
purT, b1849, JW1838
Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes two reactions: the first one is the production of beta-formyl glycinamide ribonucleotide (GAR) from formate, ATP and beta GAR; the second, a side reaction, is the production of acetyl phosphate and ADP from acetate and ATP.UniRule annotation

Catalytic activityi

Formate + ATP + 5'-phospho-ribosylglycinamide = 5'-phosphoribosyl-N-formylglycinamide + ADP + diphosphate.UniRule annotation
