Principles governing gene expression in E. coli

Caption

The availability of RNA polymerases (RNAPs) is coordinated with that of ribosomes, and the mRNA characteristics are uniform across most genes and growth conditions. These two principles prescribe a simple gene expression strategy in which protein concentrations are almost entirely controlled at the promoter level for most genes.
