Phosphoribosyl formylglycineamidine synthetase

Phosphoribosyl formylglycineamidine synthetase catalyzes the irreversible transfer of the amide group of glutamine to phosphoribosyl formylglycineamide to form the corresponding amidine. The molecular weight of the Salmonella typhimurium and chicken liver enzymes is 135,000 21). [Pg.107]
