Recent crystallographic and functional analyses of RNA enzymes have raised the possibility that the purine and pyrimidine nucleobases may function as general acid-base catalysts. However, this mode of ...
Small self-cleaving ribozymes catalyse the same reversible phosphodiester-cleavage reaction, but can adopt different structures and use distinct catalytic strategies. These catalytic RNAs do not ...
Bifunctional acid−base catalysts are highly desirable for industrially relevant chemical processes. Owing to their ability to activate electrophiles and nucleophiles simultaneously, they allow the ...
