UniProt Comments
Involved in multiple sites RNA editing events in chloroplasts. Involved in the editing of the site 7 of ndhB (ndhB-7) and site 5 of ndhD (ndhD-5) transcripts, which are two plastid-encoded subunits of the chloroplast NAD(P)H dehydrogenase (NDH) complex. Involved in the editing of the site 3 of rpoB (rpoB-3) transcript. Required for the activity of the NDH complex of the photosynthetic electron transport chain. Possesses low endoribonuclease activity in vitro.
