Mutants of Escherichia coli Defective in Ribonucleoside and Deoxyribonucleoside Catabolism

RESUMO
From Escherichia coli B, mutants were prepared that lacked the enzymes adenosine deaminase, cytidine deaminase, and purine nucleoside phosphorylase. In each case, the mutant lacked enzyme activity for both ribonucleoside and deoxyribonucleoside. Mutants lacking purine nucleoside phosphorylase lost the capacity to cleave the nucleosides of adenine, guanine, and hypoxanthine.
