Figure 7. Effect of IF3mt derivatives on the binding of [35S]fMet-tRNA to mitochondrial 28S subunits in the absence of mRNA.
(A) Reaction mixtures contained 160 nM IF2mt and increasing levels of IF3mt or its C-domain derivatives at a constant level of 28S subunits (50 nM). In the absence of IF3mt 0.1pmol of fMet-tRNA were bound to the 28S subunits by IF2mt in the reaction mixture. The estimated error of this experiment is ± 10%.
