Chemical rescue, multiple ionizable groups, and general acid–base catalysis in the HDV genomic ribozyme

In the ribozyme from the hepatitis delta virus (HDV) genomic strand RNA, a cytosine side chain is proposed to facilitate proton transfer in the transition state of the reaction and, thus, act as a general acid–base catalyst. Mutation of this active-site cytosine (C75) reduced RNA cleavage rates by a...
