In the crystal structure of the 30S ribosomal subunit from Thermus thermophilus, cysteine 24 of ribosomal protein S14 (TthS14) occupies the first position in a CXXC-X12-CXXC motif that coordinates a zinc ion. The structural and functional importance

Polyamine binding to 23S rRNA was investigated, using a photoaffinity labeling approach. This was based on the covalent binding of a photoreactive analog of spermine, N1-azidobenzamidino (ABA)-spermine, to Escherichia coli ribosomes or naked 23S rRNA

The effects of spermine on peptidyltransferase inhibition by an aminohexosylcytosine nucleoside, blasticidin S, and by a macrolide, spiramycin, were investigated in a model system derived from Escherichia coli, in which a peptide bond is formed betwe

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. Peloponnesus, Greece. One site is near the estuaries of the

Chloramphenicol is thought to interfere competitively with the binding of the aminoacyl-tRNA 3'-terminus to ribosomal A-site. However, noncompetitive or mixed-noncompetitive inhibition, often observed to be dependent on chloramphenicol concentration

S rRNA is an integral component of the large ribosomal subunit in virtually all living organisms. Polyamine binding to 5S rRNA was investigated by cross-linking of N 1 -azidobenzamidino (ABA)- spermine to naked 5S rRNA or 50S ribosomal subunits and w

Protein L4 from Thermus thermophilus (TthL4) was heterologously overproduced in Escherichia coli cells. To study the implication of the extended loop of TthL4 in the exit-tunnel and peptidyltransferase functions, the highly conserved E56 was replaced

The structural and functional importance of the highly conserved amino acid residue glutamic acid 56 (Glu56) of the ribosomal protein L4 from Thermus thermophilus (TthL4) has been investigated by replacing this residue by alanine or glutamine, and by

The effect of two photoreactive analogues of spermine, N(1)-azidobenzamidino- (ABA-) spermine and N(1)-azidonitrobenzoyl- (ANB-) spermine, on ribosomal functions was studied in a cell-free system derived from Escherichia coli. In the dark, both analo
