description | A better understanding of the molecular mechanism of protein biosynthesis still awaits a reliable model for the ribosomal particle. We describe here the application of a diffraction technique, namely three-dimensional image reconstruction from two-dimensional sheets of 70S ribosomes from
Bacillus stearothermophilus at 47 Å resolution. The three-dimensional model obtained by these studies shows clearly the two subunits, the contact points between them, an empty space large enough to accomodate the components of protein biosynthesis, the location of regions rich in RNA and a possible binding site for mRNA. The tunnel within the 50S particle which may provide the path taken by the nascent polypeptide chain in partially resolved.
Pour mieux comprendre le mécanisme moléculaire de la biosynthèse protéique il est encore nécessaire de développer un modèle solide de la particule ribosomale.
Nous présentons ici l'application d'une technique de diffraction, c'est-à-dire la reconstruction de l'image à trois dimensions des strates à deux dimensions des ribosomes 70S du
Bacillus stearothermophilus d'une résolution de 47 Å.
Le modèle à trois dimensions obtenu par ces recherches montre clairement les deux sous-unités, les points de contact entre elles, un endroit vide mais assez large à accommoder les composants de la biosynthèse protéique, la position des endroits riches en ARN et un lieu d'interaction possible de mARN. Le tunnel à travers la particule 50S qui pourrait fournir le chemin pris par la chaîne polypeptidique croissante est partiellement visible. |
