[[http://www.uniprot.org/uniprot/RL25_DEIRA RL25_DEIRA]] This is one of 3 proteins that mediate the attachment of the 5S rRNA onto the large ribosomal subunit. This protein has three domains. The N-terminal one is bound on the solvent face, the middle domain fills the space between the 5S rRNA and the L11 arm contacting the 23S rRNA while the C-terminal domain is on the edge of the intersubunit interface and contacts the A site. The protein conformation changes upon binding of a tRNA mimic to the A site, although the mimic does not interact directly with CTC itself, consistent with CTCs presumed role in moderating A site binding.[HAMAP-Rule:MF_01334] [[http://www.uniprot.org/uniprot/RL16_DEIRA RL16_DEIRA]] Binds the 5S and 23S rRNAs and is also seen to make contacts with the A and P site tRNAs. Interacts with A site tRNA mimics, and is probably one of the key factors, along with a helix of the 23S rRNA, in positioning tRNA stems in the peptidyl-transferase center.[HAMAP-Rule:MF_01342]
