RNA-binding specificity of E. coli NusA.

abstract：:In plant organelles, RNA editing alters specific cytidine residues to uridine in transcripts. All of the site-specificity factors of RNA editing identified so far are pentatricopeptide repeat (PPR) proteins. A defect in a specific PPR protein often impairs RNA editing at multiple sites, at which the cis-acting element...
