General annotation (Comments)

Function

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. HAMAP-Rule MF_01643

Catalytic activity

Formate + ATP + 5'-phospho-ribosylglycinamide = 5'-phosphoribosyl-N-formylglycinamide + ADP + diphosphate. HAMAP-Rule MF_01643

Pathway

Purine metabolism; IMP biosynthesis via de novo pathway; N(2)-formyl-N(1)-(5-phospho-D-ribosyl)glycinamide from N(1)-(5-phospho-D-ribosyl)glycinamide (formate route): step 1/1. HAMAP-Rule MF_01643

Subunit structure

Homodimer. Ref.6

Sequence similarities

Belongs to the PurK/PurT family.

Contains 1 ATP-grasp domain.
