Abstract
Staphylococcus aureus is a major opportunistic and versatile pathogen. Because the bacteria rapidly evolve multi-resistances towards antibiotics, there is an urgent need to find novel targets and alternative strategies to cure bacterial infections. Here, we provide a brief overview on the knowledge acquired on S. aureus ribosomes, which is one of the major antibiotic targets. We will show that subtle differences exist between the translation at the initiation step of Gram-negative and Gram-positive bacteria although their ribosomes display a remarkable degree of resemblance. In addition, we will illustrate using specific examples the diversity of mechanisms controlling translation initiation in S. aureus that contribute to shape the expression of the virulence factors in a temporal and dynamic manner.

Abstract
During reverse transcription of the genomic RNA of human immunodeficiency virus type 1 (HIV-1) into double-stranded DNA, reverse transcriptase (RT) must accommodate RNA-RNA, DNA-RNA, RNA-DNA and DNA-DNA hybrids as primer-template. In this study, we examined extension of RNA-tRNA3Lys, and DNA-tRNA3Lys complexes by HIV-1 RT. When the 3' end of tRNA3Lys is annealed to oligoribonucleotides, tRNA3Lys, but not the complementary RNAs, is extended by HIV-1 RT, indicating that tRNA3Lys is efficiently used as primer and RNA as template. An opposite primer usage is observed when tRNA3Lys is annealed to complementary oligodeoxyribonucleotides. In this case, the oligodeoxyribonucleotides are efficiently used as primer and tRNA3Lys as template. This result indicates that the nature of nucleic acid bound to tRNA3Lys determines which strand of the RNA-tRNA3Lys and DNA-tRNA3Lys hybrids is extended by HIV-1 RT. When an oligoribonucleotide is annealed to an unmodified transcript of tRNA3Lys, both nucleic acids are extended by HIV-1 RT, indicating that specific selection of tRNA3Lys as primer requires the post-transcriptional modifications of tRNA3Lys.

Abstract
trans-Diamminedichloroplatinum(II) was used to induce reversible cross-links between Escherichia coli initiation factor 2 (IF-2) and fMet-tRNA(f)(Met). Two distinct cross-links between IF-2 and the initiator tRNA were produced. Analysis of the cross-linking regions on both RNA and protein moieties reveals that the T arm of the tRNA is in the proximity of a region of the C-terminal domain of IF-2 (residues Asn611-Arg645). This cross-link is well-correlated with the fact that the C-domain of IF-2 contains the fMet-tRNA binding site and that the cross-linked RNA fragment precisely maps in a region which is protected by IF-2 from chemical modification and enzymatic digestion. Rather unexpectedly, a second cross-link was characterized which involves the anticodon arm of fMet-tRNA(f)(Met) and the N-terminal part of IF-2 (residues Trp215-Arg237).

Abstract
The synthesis and purification of short model messenger RNAs modified with undecagold cluster are described. A monoamino undecagold cluster was introduced on the oxidized 3' cis-glycol group of the mRNA followed by reduction of the formed Schiff's base. The stability of the modified mRNA under the conditions used for in vitro messenger RNA translation is studied. The possibility of the formation of a specific translational initiation complex with bacterial ribosomes and modified mRNAs is shown. The results of these experiments indicate that the attachment of an undecagold cluster to a mRNA is a useful tool for electron microscopic and crystallographic studies.

Abstract
70S ribosomes from Thermus thermophilus are able to form ternary complexes with N-AcPhe-tRNAPhe from either Thermus thermophilus or Escherichia coli, in the presence of a short oligo(U) of six or nine uridines. A complex of N-AcPhe-tRNAPhe/(U)9/70S ribosome from Th. thermophilus was crystallized under the same conditions used for the growth of crystals from isolated ribosomes (S.D. Trakhanov, et al., (1987) FEBS Lett. 220, 319-322).
