ppr53

Chloroplast-localized PPR-SMR protein that binds to and stabilizes the 5� end of a pre-23S rRNA isoform and also promotes the stabilization and translation of a specific processed ndhA mRNA. The absence of PPR53 results in severely chlorotic seedlings, a strong reduction in chloroplast ribosomes and a global loss of chloroplast translation products.
