Protein
50S ribosomal protein L23
Organism
Escherichia coli (strain K12)
Function
One of the early assembly proteins, it binds 23S rRNA; is essential for growth. One of the proteins that surround the polypeptide exit tunnel on the outside of the subunit. Acts as the docking site for trigger factor (PubMed:12226666) for Ffh binding to the ribosome (SRP54, PubMed:12756233 and PubMed:12702815) and to nascent polypeptide chains (PubMed:12756233).
Similarity
Belongs to the universal ribosomal protein uL23 family.
