Prs (phosphoribosyl pyrophosphate synthase) is a broadly conserved protein that synthesises 5-phosphoribosyl 1-pyrophospate (PRPP); a substrate for biosynthesis of at least 10 enzymatic pathways including biosynthesis of DNA building blocks - purines and pyrimidines. In Escherichia coli, it is a protein of homo-hexameric quaternary structure, which can be challenging to work with, due to frequent aggregation and activity loss. Several studies showed brief purification protocols for various bacterial PRPP synthases, i
