Invariant Distribution of Promoter Activities in Escherichia coli
Figure 6
Model for resource allocation between ribosomal and metabolic proteins.
Scaled growth rate (α/vC) as a function of the fraction of ribosomal constituents φ = R/C. Growth rate is maximal at intermediate levels of φ (filled circles). Richer environments (lower parameter A in the model) have higher optimal growth rates and a higher optimal φ. The relation between the maximal growth rate and the ribosomal fraction at which the maximum is obtained is linear (black line).
