Introduction Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. Significance of glutamine for biosynthesis of purines and pyrimidines - It is donor of amino group Why the cells with high mitotic rate consume high amounts of glutamine? C2 & C8 from formate of N10 - formyl THF. Additionally, free purines and pyrimidines can be degraded, the purines to the oxidized ring compound uric acid and the pyrimidines to smaller compounds (β‐amino acids, not the α‐amino acids found in proteins). The first three enzymes of the process are all coded by the same gene in CAD which consists of carbamoyl phosphate synthetase II, aspartate carbamoyltransferase and dihydroorotase. Shorter pathway Base is made first, then attached to ribose-P (unlike purine biosynthesis) Only 2 precursors (aspartate and glutamate + HCO3 - ) contribute to the 6-membered ring The product is OMP (orotydilate) 3. 1.
