Formylglycinamidine ribotide

The amino acid antagonists broadly act as a glutamine antagonists in the synthesis of formylglycinamidine ribotide from glutamine and formylglycinamide ribotide.

The amination of UTP [Eq. (2)] and the synthesis of utamine 282) and glutathione 288) serve as examples. Other kinds of nucleotides may be required, such as GTP for the synthesis of adenylosuccinate from ino-sinic and aspartic acids [Eq. (3)] IS). Cyclizing reactions such as the conversion of iV-formylglycinamidine ribotide to 4-aminoimidazole ribotide also require ATP [Eq. (66)] 284)-H...
