Figure 4.
Figure 4. Time-course for glutamylation of E. coli tRNA[2]^Gln by GlnRS. The inset shows a thin-layer chromatography plate in which misacylated Glu-AMP is formed to approximately 50% aminoacylation levels (see Materials and Methods for details). The % aminoacylation on the ordinate is derived from the ratio of intensities of the spots corresponding to Glu-AMP and AMP (right).
