MetaCyc Polypeptide: 50S ribosomal subunit protein L23

Gene: rplW Accession Numbers: EG10883 (MetaCyc), b3318, ECK3305

Species: Escherichia coli K-12 substr. MG1655

Component of:
50S ribosomal subunit
ribosome

Summary:
The L23 protein is a component of the 50S subunit of the ribosome and provides a chaperone docking site that links protein biosynthesis with protein folding. L23 is essential for growth of E. coli [Kramer02].

L23 crosslinks to Trigger Factor (TF), a protein that interacts with nascent polypeptides on the ribosome, and is essential for the association of TF with the ribosome [Kramer02, Ullers03]. It also crosslinks to the Ffh component of the Signal Recognition Particle (SRP) [Gu03a, Ullers03]. Kd values for binding of TF and SRP to the ribosome under various conditions have been estimated, and TF and SRP are thought to have separate binding sites on L23 [Raine04]. L23 can also be crosslinked to a nascent peptide chain [Houben05].

L23 is an early assembly protein that interacts with 23S rRNA [Marquardt79, Osswald90, Egebjerg91, Chistyakov89, Tumminia94, Thiede98, Skold81, Vester84, Thiede98]. L23 crosslinks to tRNA in the A site [Graifer89]. L23 can also be crosslinked to L34 [Walleczek89, Walleczek89a] and L29 [Walleczek89a].

L23 is photoaffinity labeled by puromycin, thus placing it within the A-site domain of the peptidyl transferase center [Cooperman75, Jaynes78, Weitzmann85]. Puromycin-crosslinked L23 interferes with tRNA binding, but 50S subunits containing it retain peptidyl transferase activity [Weitzmann90].
