Protein attributes

Sequence length	118 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit By similarity. HAMAP-Rule MF_00382
Sequence similarities	Belongs to the ribosomal protein L20P family.
