Abstract
We have developed a cell-free system ofE. colithat enables us to study thein vitrotranslation of natural mRNA mediated by wild-type or mutant EF-Tu. Various mutant EF-Tu species have been analyzed, one of which, EF-Tu [G222D], appeared to be virtually unable to mediate the translation of natural mRNA. Since this mutant factor is able to participate in translationin vivoby suppressing nonsense and frameshift mutations in cooperation with EF-Tu [A375T], a revision of the generally accepted scheme of the elongation cycle has been proposed (Bosch, L., Vijgenboom, E., & Zeef, L.A.H., 1996,Biochemistry36).
