Reconstitution in vitro of the valyl-tRNA synthetase-elongation factor (EF) 1 beta gamma delta complex. Essential roles of the NH2-terminal extension of valyl-tRNA synthetase and of the EF-1 delta
Valyl-tRNA synthetase from mammalian cells is isolated exclusively as a complex with elongation factor (EF) 1H (the "heavy" form of eukaryotic EF-1, composed of subunits alpha, beta, gamma, andExpand

LE VIADUC DE FRAIS VALLON - UNE TECHNIQUE INNOVANTE POUR LA CONSTRUCTION DE DALLES NERVUREES
Le projet du viaduc de Frais Vallon s'inscrit dans le cadre de la construction de la rocade autoroutiere de Marseille. Cette rocade, deja envisagee dans les annees 30, ne fut elaboree qu'a la fin desExpand
La valyl-arnt synthetase d'eucaryotes superieurs est associee ave le facteur d'elongation eef-1h : caracterisation structurale et fonctionnelle du complexe
Chez les eucaryotes superieurs, la valyl-arnt synthetase (valrs) est associee au facteur d'elongation eef-1h. Afin de preciser les bases structurales et fonctionnelles de cette association, nousExpand
