MetaCyc Pathway: superpathway of histidine, purine, and pyrimidine biosynthesis

If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.

Superclasses: Superpathways

Some taxa known to possess this pathway include ? : Escherichia coli K-12 substr. MG1655

Expected Taxonomic Range: Bacteria

Summary:
Pyrimidine, purine, and pyridine nucleotide synthesis all require phosphoribosylpyrophosphate (PRPP) as a precursor. PRPP is utilized by both the de novo pathways and the auxiliary or salvage pathways by which endogenously formed or exogenously added pyrimidine, purine, or pyridine bases are converted to the corresponding ribonucleoside monophosphates by phosphoribosyltransferases. PRPP is also used in the histidine and tryptophan biosynthesis pathways. PRPP thus may be regarded as a precursor for the synthesis of nucleic acids, proteins, and for the NAD(P) coenzymes. The formation of PRPP therefore is subjected to strict metabolic control [HoveJensen86].
