Publisher Summary This chapter describes the purification procedure of purine nucleoside phosphorylase (PNPase) enzyme from human erythrocytes. PNPase is crystallized from human erythrocytes, where it is present in relatively high concentration (about 13 units/ml packed cells). PNPase is essential for the reutilization of purine ribo- and deoxyribonucleosides in these cells that lack the de novo pathway for nucleotide synthesis. The enzyme is found deficient in erythrocytes and lymphocytes of… Expand
