CC   -!- FUNCTION: One of the primary rRNA binding proteins, it binds directly
CC       near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S
CC       subunit. {ECO:0000250}.
CC   -!- SUBUNIT: Part of the 50S ribosomal subunit.
CC   -!- SUBCELLULAR LOCATION: Plastid, cyanelle.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uL3 family.
CC       {ECO:0000305}.
