Binds and cleaves RNA, particularly in stem-loops. Associates with pre-ribosomal particles in chloroplasts, and participates in chloroplast ribosomal RNA metabolism, probably during the final steps of 23S rRNA maturation. May enhance transcription by the plastid-encoded polymerase and translation in plastid via the stabilization of ribosome assembly intermediates. Required for chloroplast integrity. Involved in the regulation of the circadian system. Involved in the regulation of heteroglycans and monosaccharide mobilization. Required for full expression of genes transcribed by the plastid-encoded RNA polymerase (PEP). Essential for embryo development (PubMed:25161659).

Belongs to the NAD(P)-dependent epimerase/dehydratase family.
