Protein attributes

Sequence length	103 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	One of the early assembly proteins it binds 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome. Forms the main docking site for trigger factor binding to the ribosome By similarity. HAMAP MF_01369_B
Subunit structure	Part of the 50S ribosomal subunit. Contacts protein L29, and trigger factor when it is bound to the ribosome By similarity.
Sequence similarities	Belongs to the ribosomal protein L23P family.
