Figure 1From: Phosphoribosyl pyrophosphate synthetase activity affects growth and riboflavin production in Ashbya gossypiiMetabolic contribution of PRPP to the purine biosynthesis and other anabolic pathways. The purine pathway is shaded; the de novo purine pathway starts with PRPP biosynthesis, while salvage pathways use PRPP to transform purine bases to monophosphate nucleotides. Dashed arrows indicate a multi-step pathway; sAMP, adenylosuccinate.Back to article page
