Dissecting the ribosomal inhibition mechanisms of edeine and pactamycin: the universally conserved residues G693 and C795 regulate P-site RNA binding.
The crystal structures of the universal translation-initiation inhibitors edeine and pactamycin bound to ribosomal 30S subunit have revealed that edeine induces base pairing of G693:C795, residuesExpand

Translational responses of Mytilus galloprovincialis to environmental pollution: integrating the responses to oxidative stress and other biomarker responses into a general stress index.
Heavy metals are commonly associated with the generation of reactive oxygen species (ROS), which may cause oxidative damage to several cellular macromolecules and organelles. In an attempt toExpand

Translational responses and oxidative stress of mussels experimentally exposed to Hg, Cu and Cd: one pattern does not fit at all.
Certain metals, like Hg, Cu and Cd, are capable of down-regulating protein synthesis in several marine organisms, including Mytilus galloprovincialis. Nevertheless, due to the complexity of theExpand

Chloramphenicol Derivatives as Antibacterial and Anticancer Agents: Historic Problems and Current Solutions
Chloramphenicol (CAM) is the D-threo isomer of a small molecule, consisting of a p-nitrobenzene ring connected to a dichloroacetyl tail through a 2-amino-1,3-propanediol moiety. CAM displays aExpand

Deacylated tRNA is released from the E site upon A site occupation but before GTP is hydrolyzed by EF-Tu
The presence or absence of deacylated tRNA at the E site sharply influences the activation energy required for binding of a ternary complex to the ribosomal A site indicating the differentExpand

Time-resolved binding of azithromycin to Escherichia coli ribosomes.
Azithromycin is a semisynthetic derivative of erythromycin that inhibits bacterial protein synthesis by binding within the peptide exit tunnel of the 50S ribosomal subunit. Nevertheless, there isExpand

The identification of spermine binding sites in 16S rRNA allows interpretation of the spermine effect on ribosomal 30S subunit functions
TLDR
A photoreactive analogue of spermine, N1-azidobenzamidino (ABA)-spermine was covalently attached after irradiation to Escherichia coli 30S ribosomal subunits or naked 16S rRNA. Expand

Kinetic studies on ribosomal peptidyltransferase. The behaviour of the inhibitor blasticidin S.
In a cell-free system derived from Escherichia coli, the reaction between Ac[3H]Phe-tRNA and puromycin (S) is inhibited by blasticidin S (I). In this reaction Ac[3H]Phe-tRNA is part of theExpand

Inhibition of ribosomal peptidyltransferase by chloramphenicol
The mechanism of action of chloramphenicol in inhibiting peptide bond formation has been examined with the aim of discovering whether chloramphenicol brings about conformational changes in theExpand

Biomonitoring of Gulf of Patras, N. Peloponnesus, Greece. Application of a biomarker suite including evaluation of translation efficiency in Mytilus galloprovincialis cells.
Specimens of Mytilus galloprovincialis were placed in bow nets and immersed at 3-10 m depth in a clean coastal region (reference area), Itea, and two marine stations along Gulf of Patras, N.Expand
