The Genomic Pattern of tDNA Operon Expression in E. coli
Figure 1
Regression of tRNA Isoacceptor Concentrations at the Highest Measured Growth Rate for E. coli Strain W1485 (A K12 Derivative) against the Same at Lower Growth Rates
tRNA concentrations at the highest growth rate (μ = 2.5 doublings/h) are regressed against the same at (A) μ = 0.4 doublings/h and at (B) μ = 0.7 doublings/h. Concentration data are from [2]. Classification into “major,” “minor,” and “neither” types is from codon usage in ribosomal protein genes and anticodon reading relationships from [2,9]. All isoacceptors increase with growth rate, so that the uniform increase of all isoacceptors swamps variation in increase of individual isoacceptors.
