A nucleobase-binding pocket in a viral RNA-dependent RNA polymerase contributes to elongation complex stability.

abstract：:Non-coding RNAs (ncRNAs) have diverse essential biological functions in all organisms, and in eukaryotes, two such classes of ncRNAs are the small nucleolar (sno) and small nuclear (sn) RNAs. In this study, we have identified and characterized a collection of sno and snRNAs in Giardia lamblia, by exploiting our discov...
