CC   -!- FUNCTION: Involved in the de novo purine biosynthesis. Catalyzes the
CC       transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing
CC       5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by
CC       PurU via hydrolysis of 10-formyl-tetrahydrofolate. PurT is also able to
CC       cleave acetyl phosphate and carbamoyl phosphate to produce ATP with
CC       acetate and carbamate, respectively. {ECO:0000269|PubMed:8117714,
