CC   -!- FUNCTION: One of the primary rRNA binding proteins. Required for
CC       association of the 30S and 50S subunits to form the 70S ribosome, for
CC       tRNA binding and peptide bond formation. It has been suggested to have
CC       peptidyltransferase activity; this is somewhat controversial. Makes
CC       several contacts with the 16S rRNA in the 70S ribosome.
CC       {ECO:0000255|HAMAP-Rule:MF_01320}.
CC   -!- SUBUNIT: Part of the 50S ribosomal subunit. Forms a bridge to the 30S
CC       subunit in the 70S ribosome. {ECO:0000255|HAMAP-Rule:MF_01320}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uL2 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01320}.
