Pyrimidin ist eine sechsgliedrige heterocyclische aromatische organische Verbindung mit zwei Stickstoffatomen, die nach der systematischen Nomenklatur auch als 1,3-Diazin bezeichnet wird. 2 Hintergrund Bei der Pyrimidinbiosynthese wird, im Gegensatz zur Purinbiosynthese, zuerst der Ring synthetisiert und erst anschließend der Ring mit der Ribose verbunden. Conflicts of interest. • The six members pyrimidine ring is made first and then attached to ribose-5-monophosphate. The first three enzymes and the fifth and sixth enzymes are part of two multifunctional peptides to increase efficiency. The pyrimidine synthesis is a similar process than that of Purines(Purines Synthesis).In the de novo synthesis of Pyrimidines, the ring is synthesized first and then it is attached to a ribose-phosphate to for a pyrimidine nucleotide.Pyrimidine rings are assembled from bicarbonate, aspartate, and Ammonia. There are two major synthetic pathways, for purine and pyrimidine bases, respectively, both of which diverge towards their ends to produce the different variants. 1. Synthesis from AmidineSynthesis from Amidine 9. 2. The pyrimidine synthesis pathway is controlled by feedback inhibition by UTP acting on the CPSII domain of the CAD trifunctional enzyme (Figure 2, Table 1) (5, 11), which is also activated by PRPP, thereby integrating regulation of purine and pyrimidine biosynthesis .
