Abstract
PUF and PPR proteins are two families of α-helical repeat proteins that recognize single-stranded RNA sequences. Both protein families hold promise as scaffolds for designed RNA-binding domains. A modular protein RNA recognition code was apparent from the first crystal structures of a PUF protein in complex with RNA, and recent studies continue to advance our understanding of natural PUF protein recognition (de-coding) and our ability to engineer specificity (re-coding). Degenerate recognition motifs make de-coding specificity of individual PPR proteins challenging. Nevertheless, re-coding PPR protein specificity using a consensus recognition code has been successful.
