Purine biosynthesis pathway

Molecular classification
Metabolic pathway, involving enzymes
01

Overview

The purine biosynthesis pathway is a metabolic process that generates purine nucleotides, such as adenosine monophosphate (AMP) and guanosine monophosphate (GMP), from simpler precursors like phosphoribosyl pyrophosphate (PRPP) and amino acids. This pathway is crucial for nucleic acid synthesis and cell proliferation, and its dysregulation can contribute to various diseases, including cancer and gout. Enzymes within this pathway can be targeted therapeutically to modulate purine metabolism in disease states.
