title: SPECIFICITY OF POTASSIUM-ACTIVATED PHOSPHODIESTERASE OF ESCHERICHIA COLI.
abstract: A potassium-activated phosphodiesterase that hydrolyzes polyribonucleotides to 5'-mononucleotides has been purified approximately 600-fold from extracts of Escherichia coli B. The purified enzyme appears to be specific for single-stranded polyribonucleotides: helical forms are not hydrolyzed, nor do they inhibit the hydrolysis of single-stranded chains.
