Webtested whether diphthamide biosynthesis can be restored in Δylr143w strain by introducing YLR143W back to the cells. When Δylr143w was transformed with YLR143W, diphthamide can be detected by the labeling with low concentration of DT and Rh-NAD (Fig. 3D and Fig. S6). Transformation with an empty vector failed to restore diphthamide biosynthesis. WebDiphthamide has been found to be important in maintaining translational fidelity, helping eEF2 to maintain the integrated conformation. The lack of diphthamide results in elevated frameshift in protein synthesis. Diphthamide has also been found to involve in growth and development, with developmental defects in the deficiency of diphthamide.
