Crystal structure of the bacterial ribosome from escherichia coli in complex with the antibiotic kasugamyin at 3.5A 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
The prokaryotic ribosome is an important target of antibiotic action. We, determined the X-ray structure of the aminoglycoside kasugamycin (Ksg) in, complex with the Escherichia coli 70S ribosome at 3.5-A resolution. The, structure reveals that the drug binds within the messenger RNA channel of, the 30S subunit between the universally conserved G926 and A794, nucleotides in 16S ribosomal RNA, which are sites of Ksg resistance. To, our surprise, Ksg resistance mutations do not inhibit binding of the drug, to the ribosome. The present 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-tRNA, sites (P and E sites).
About this Structure
1VS5 is a Protein complex structure of sequences from Escherichia coli with KSG and MG as ligands. Full crystallographic information is available from OCA.
