case <OC:Bacteria>
FUNCTION This protein binds specifically to 23S rRNA; its binding is stimulated by other ribosomal proteins, e.g., L4, L17, and L20. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome (By similarity).
else case <OC:Archaea>
FUNCTION This protein binds specifically to 23S rRNA. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome (By similarity).
else case <OG:Chloroplast>
FUNCTION This protein binds specifically to 23S rRNA (By similarity).
end case
FUNCTION The globular domain of the protein is located near the polypeptide exit tunnel on the outside of the subunit, while an extended beta-hairpin is found that lines the wall of the exit tunnel in the center of the 70S ribosome (By similarity).
SUBUNIT Part of the 50S ribosomal subunit (By similarity).
case <OG:Chloroplast>
SUBCELLULAR LOCATION Plastid, chloroplast.
end case
SIMILARITY Belongs to the ribosomal protein L22P family.
