WebPurine nucleoside phosphorylase can metabolize adenosine to adenine, inosine to hypoxanthine, and guanosine to guanine, and produce ribose-5-phosphate in these reactions. It should be noted that the acronym PNPase is also used for another unrelated enzyme, Polynucleotide Phosphorylase. Web, polynucleotide phosphorylase regulates mRNA processing either by adding ribonucleotides to the 3’ end or by cleaving bases in 3’ to 5’ direction. The function of PNPase depends upon inorganic phosphate (Pi) concentration inside the cell. The transcripts are polyadenylated using enzyme polyadenylate polymerase I (PAPI).
