Crystal structure of the bacterial ribosome from Escherichia coli at 3.5 A resolution. This file contains the 30S subunit of one 70S ribosome. The entire crystal structure contains two 70S ribosomes and is described in remark 400.
Overview
We describe two structures of the intact bacterial ribosome from, Escherichia coli determined to a resolution of 3.5 angstroms by x-ray, crystallography. These structures provide a detailed view of the interface, between the small and large ribosomal subunits and the conformation of the, peptidyl transferase center in the context of the intact ribosome., Differences between the two ribosomes reveal a high degree of flexibility, between the head and the rest of the small subunit. 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 (mRNA) and transfer, RNAs (tRNAs) during translocation.
About this Structure
2AVY is a Protein complex structure of sequences from Escherichia coli with MG as ligand. Full crystallographic information is available from OCA.
