The presence of a second purine nucleoside phosphorylase in wild-type strains of E. coli K-12 after growth on xanthosine has been demonstrated. Like other purine nucleoside phosphorylases it is able to carry out both phosphorylosis and synthesis of purine deoxy- and ribonucleosides whilst pyrimidine nucleosides cannot act as substrates. In contrast to the… CONTINUE READING
