Information costs in the control of protein synthesis.

Efficient protein synthesis depends on the availability of charged tRNA molecules. With 61 different codons, shifting the balance among the tRNA abundances can lead to large changes in the protein synthesis rate. Previous theoretical work has asked about the optimization of these abundances, and there is some evidence that regulatory mechanisms bring cells close to this optimum, on average. We formulate the tradeoff between the precision of control and the efficiency of synthesis, asking for…

Does Escherichia coli optimize the economics of the translation process?

Highly expressed genes, which produce 80-90% of the protein mass in the E. coli cell, appear to have selected codons which make an optimal use of the tRNA pool, which allows the relative rate constants of synonymous codons to be computed.

Maximizing transcription efficiency causes codon usage bias.

An optimality model of the transcriptional process is presented with the prediction that the most frequently used ribonucleotide at the third codon sites in mRNA molecules should be the same as the most abundant ribon nucleotide in the cellular matrix where mRNA is transcribed.

Information flow and optimization in transcriptional regulation

Although the simplified problem of a single gene responding to a single TF is considered, it is found that these predictions are in surprisingly good agreement with recent experiments on the Bicoid/Hunchback system in the early Drosophila embryo and that this system achieves ∼90% of its theoretical maximum information transmission.

Information capacity of genetic regulatory elements.

Information theory is used to formalize the notion of information transmission in simple genetic regulatory elements in the presence of physically realistic noise sources and demonstrates that capacities significantly greater than one bit are possible, so that transcriptional regulation need not be limited to simple "on-off" components.

Quantifying the entropic cost of cellular growth control.

This work quantifies the amount of regulation required to control growth in living cells by a Maximum Entropy approach to the space of underlying metabolic states described by genome-scale models and connects the ‘inverse temperature’ that controls MaxEnt distributions to the growth dynamics.

Maximum entropy modeling of metabolic networks by constraining growth-rate moments predicts coexistence of phenotypes.

Maximum entropy distributions in the space of steady states of metabolic networks are considered upon constraining the first and second moments of the growth rate, opening the possibility to detect coexistence from flux data.

Growth against entropy in bacterial metabolism: the phenotypic trade-off behind empirical growth rate distributions in E. coli

This work shows that empirical growth rate distributions recently obtained in experiments at single-cell resolution can be explained in terms of a trade-off between the higher fitness of fast-growing phenotypes and the higher entropy of slow-growing ones.

Statistical mechanics for metabolic networks during steady state growth

A generalization of flux balance analysis to single cells based on maximum entropy modeling is applied, and it is found that growth rate fluctuations of E. coli reflect metabolic flux variability and growth sub-optimality, in turn highlighting information costs for growth optimization.

Escherichia coli K-12 undergoes adaptive evolution to achieve in silico predicted optimal growth

When placed under growth selection pressure, the growth rate of E. coli on glycerol reproducibly evolved from a sub-optimal value to the optimal growth rate predicted from a whole-cell in silico model, opening the possibility of using adaptive evolution of entire metabolic networks to realize metabolic states that have been determined a priori based on insilico analysis.

The E. coli molecular phenotype under different growth conditions

A detailed, genome-wide transcriptomics and proteomics dataset of E. coli grown under 34 different conditions is presented, finding numerous differentially expressed genes for growth on gluconate and under salt and magnesium stress.
