Optimal Noise Filtering in the Chemotactic Response of Escherichia coli
Figure 8
Model of E. coli Signaling Network
A model of the bacterial signaling network is shown for a cluster of N receptors with M methylation sites each. The receptor cluster can exist in a ligand bound or unbound form, each with up to a total of NM sites methylated. The methylation (demethylation) rate of a particular state is proportional to the probability of the state being inactive (active).
