Phosphorothioate lambda exonuclease
WebOct 4, 2024 · Synthetic phosphorothioate (PT) internucleotide linkages, in which a nonbridging oxygen is replaced by a sulphur atom, share similar physical and chemical properties with phosphodiesters but confer enhanced nuclease tolerance on DNA/RNA, making PTs a valuable biochemical and pharmacological tool. WebPhosphorothioates have found their usefulness in the general area of oligonucleotide therapeutic applications. Initially this modification was introduced into the antisense methodology because of the nuclease resistance of the phosphorothioate linkage in comparison with that of the phosphate linkage …

WebJan 14, 2014 · The phosphorothioate (PS) bond substitutes a sulfur atom for a non-bridging oxygen in the phosphate backbone of an oligonucleotide. Approximately 50% of the time (due to the 2 resulting stereoisomers that can form), PS modification renders the internucleotide linkage more resistant to nuclease degradation. WebHere, based on lambda exonuclease (λ exo), for the first time, we propose the normally open (NO) and normally closed (NC) switching strategy with a unified signal transmission mechanism to build molecular circuits. Specifically, the opposite logic can be output with or without a single signal, and the state of the switch can be adjusted by the ...
WebAntisense phosphorothioate oligonucleotide therapies are a promising treatment for a number of diseases, including cancer, diabetes, high cholesterol, and AIDS. The inherently unique characteristics of phosphorothioate oligonucleotides, combined with the multiple-step manufacturing process, make analysis of these oligonucleotides challenging.
