UniProt Comments
Required for proper chloroplast development (Ref. 7, PubMed:24144791). Involved in the regulation of plastid gene expression probably through regulation of plastid-encoded polymerase (PEP) dependent chloroplast transcription (PubMed:24144791). Required for RNA editing of several chloroplastic transcripts, especially accD transcripts (PubMed:24144791, PubMed:26123918). Required for processing of the chloroplastic rpoA pre-mRNA (Ref. 6, Ref. 7). Required for the monocistronic rpoA transcript processing from the rpl23-rpl2-rps19-rpl22-rps3-rpl16-rpl14-rps8-rpl36-rps11-rpoA polycistron. Binds the intergenic sequence of rps11-rpoA for rpoA monocistronic RNA cleavage (Ref. 7).
