Biosynthesis of Purine Nucleotide

Biosynthesis of Purine Nucleotide

Biosynthesis of Purine Nucleotide refers to the cellular process by which purine nucleotides primarily adenosine monophosphate (AMP) and guanosine monophosphate (GMP) are synthesized from small molecular precursors. Biosynthesis of Purine Nucleotide pathway involves the stepwise construction of the purine ring directly onto a ribose sugar molecule (from PRPP: 5-phosphoribosyl-1-pyrophosphate), utilizing amino acids (like glycine, glutamine, and … Read more
