TL;DR: Swiveling of the head of the small subunit observed in the present structures, coupled to the ratchet-like motion of the two subunits observed previously, suggests a mechanism for the final movements of messenger RNA and transfer RNAs during translocation.

TL;DR: It can be concluded that practices that include reduced tillage and crop residue retention can be adopted as safer agricultural practices to preserve and improve the diversity of soil bacterial communities.

TL;DR: Structural and biochemical data are presented showing that protein Y, an Escherichia coli stress protein, fills the tRNA- and mRNA-binding channel of the small ribosomal subunit to stabilize intact ribosomes and the mechanism used by protein Y to reduce translation initiation during stress and quickly release ribosome for renewed translation initiation may therefore occur widely in nature.

TL;DR: Structural and biochemical results indicate that inhibition by Ksg and Ksg resistance are closely linked to the structure of the mRNA at the junction of the peptidyl-tRNA and exit-t RNA sites (P and E sites).

TL;DR: These 70S ribosome structures indicate that mRNA decoding is coupled primarily to movement of the small subunit body, consistent with previous proposals, whereas closing of the head and the helical switch may function in other steps of protein synthesis.
