1CLI - PubMed Abstract: 
The purine biosynthetic pathway in procaryotes enlists eleven enzymes, six of which use ATP. Enzymes 5 and 6 of this pathway, formylglycinamide ribonucleotide (FGAR) amidotransferase (PurL) and aminoimidazole ribonucleotide (AIR) synthetase (PurM) utilize ATP to activate the oxygen of an amide within their substrate toward nucleophilic attack by a nitrogen ...
