Function

function

Transcription termination factor required for processing and steady-state levels of plastid transcripts. Required for splicing of the chloroplastic Clp protease (ClpP) group IIa intron. Required for maturation of 16S rRNA and 23S rRNA in the chloroplast. Essential for embryogenesis (PubMed:21464319).
Required for the maintenance of the correct levels of transcripts in the mitochondria and chloroplasts

Miscellaneous

'BELAYA SMERT' means white death in Russian.
