RRF domain I in complex with the 50S ribosomal subunit from Deinococcus radiodurans

Structural highlights

1y69 is a 4 chain structure with sequence from [1], Deinococcus radiodurans (strain atcc 13939 / dsm 20539 / jcm 16871 / lmg 4051 / nbrc 15346 / ncimb 9279 / r1 / vkm b-1422) and Deinococcus radiodurans r1. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[RL27_DEIRA] Binds the 5S and 23S rRNAs and also the tRNA in the P site.[HAMAP-Rule:MF_00539] [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] [RRF_ECOLI] Responsible for the release of ribosomes from messenger RNA at the termination of protein biosynthesis. May increase the efficiency of translation by recycling ribosomes from one round of translation to another.[HAMAP-Rule:MF_00040]

Publication Abstract from PubMed

This study presents the crystal structure of domain I of the Escherichia coli ribosome recycling factor (RRF) bound to the Deinococcus radiodurans 50S subunit. The orientation of RRF is consistent with the position determined on a 70S-RRF complex by cryoelectron microscopy (cryo-EM). Alignment, however, requires a rotation of 7 degrees and a shift of the cryo-EM RRF by a complete turn of an alpha-helix, redefining the contacts established with ribosomal components. At 3.3 A resolution, RRF is seen to interact exclusively with ribosomal elements associated with tRNA binding and/or translocation. Furthermore, these results now provide a high-resolution structural description of the conformational changes that were suspected to occur on the 70S-RRF complex, which has implications for the synergistic action of RRF with elongation factor G (EF-G). Specifically, the tip of the universal bridge element H69 is shifted by 20 A toward h44 of the 30S subunit, suggesting that RRF primes the intersubunit bridge B2a for the action of EF-G. Collectively, our data enable a model to be proposed for the dual action of EF-G and RRF during ribosome recycling.
