CC   -!- FUNCTION: Binds directly to 23S ribosomal RNA and is necessary for the
CC       in vitro assembly process of the 50S ribosomal subunit. It is not
CC       involved in the protein synthesizing functions of that subunit.
CC       {ECO:0000255|HAMAP-Rule:MF_00382}.
CC   -!- SUBCELLULAR LOCATION: Plastid, organellar chromatophore.
CC   -!- SIMILARITY: Belongs to the bacterial ribosomal protein bL20 family.
CC       {ECO:0000255|HAMAP-Rule:MF_00382}.
