Phosphoribosylpyrophosphate (PRibPP) is the primary precursor in the biosynthesis of purine and pyrimidine nucleotides. The synthesis of PRibPP is catalysed by a ubiquitous PRibPP synthetase in many organisms. We provide evidence that a cyanobacterium, Synechococcus sp., has a gene encoding a protein with striking homology to mammalian PRibPP synthetases.

D000458	Cyanobacteria	A phylum of oxygenic photosynthetic bacteria comprised of unicellular to multicellular bacteria possessing CHLOROPHYLL a and carrying out oxygenic PHOTOSYNTHESIS. Cyanobacteria are the only known organisms capable of fixing both CARBON DIOXIDE (in the presence of light) and NITROGEN. Cell morphology can include nitrogen-fixing heterocysts and/or resting cells called akinetes. Formerly called blue-green algae, cyanobacteria were traditionally treated as ALGAE.
