Abstract

Three enzymes in Escherichia coli which break down ribonucleic acid are now known. One is polynucleotide phosphorylase (I), which in the presence of phosphate yields ribonucleoside 5’-diphosphates. A ribonuclease, which will be called ribonuclease I, is bound to 30 S ribosomes in latent form. When released from the ribosomes it attacks RNA to yield… (More)
