WebbThe translocation step of protein elongation entails a large-scale rearrangement of the tRNA-mRNA-ribosome complex. Recent years have seen major advances in unraveling the mechanism of the process on the molecular level. A number of intermediate states have been defined and, in part, characterized structurally. WebbLa translocation, en biologie, décrit deux mécanismes : une étape lors de la synthèse des protéines , lorsque le ribosome se décale de trois nucléotides vers l'extrémité 3' de l'ARN messager....
