Nucleobase-mediated general acid-base catalysis in the Varkud satellite ribozyme

Existing evidence suggests that the Varkud satellite (VS) ribozyme accelerates the cleavage of a specific phosphodiester bond using general acid-base catalysis. The key functionalities are the nucleobases of adenine 756 in helix VI of the ribozyme, and guanine 638 in the substrate stem loop. This re...
