1NZ1, 1SY4 - PubMed Abstract: 
Phosphorothioate-substitution experiments are often used to elucidate functionally important metal ion-binding sites on RNA. All previous experiments with S(P)-phosphorothioate-substituted RNAs have been done in the absence of structural information for this particular diastereomer ...
