RNA precursor molecules and ribonucleases in E. coli
Copyright policy )RNA precursor molecules and ribonucleases in E. coli
The post-transcriptional alteration of oneE. coli RNA species (tyrosine tRNA) by nucleases is now understood in some detail. Knowledge of this pathway has allowed us to speculate on the nature and control of the processing of otherE. coli RNA species by the combined attack of endo- and exo-nucleolytic ribonucleases. A review of the properties of knownE. coli ribonucleases has led us consider which of these activities might be capable of functioning together in different pathways. The control of these nuclease activities (singly or in groups) may be exerted through structural transitions of RNA substrates or through ionic or protein cofactors.
