WebThe introduction of non-bridging phosphorothioate (PS) linkages in oligonucleotides has been instrumental for the development of RNA therapeutics and antisense oligonucleotides. WebAbstract Genomic modification by sulfur in the form of phosphorothioate (PT) is widespread among prokaryotes, including human pathogens. Apart from its physiological functions, PT sulfur has redox and nucleophilic properties that suggest effects on bacterial fitness in stressful environments.
