Effects of CheR localisation and gene expression noise, as well as correlated ligand noise on noise power spectrum. (A) Total power spectrum of the motor excluding CheR localisation and gene expression noise (black line), and contributions to the motor power spectrum from receptor methylation and demethylation (green solid line), CheR localisation (dashed line) and gene expression noise (dotted line). (B) Total power spectrum of the motor excluding correlated ligand noise (solid black line), and contributions to the motor power spectrum from uncorrelated ligand noise at receptor complexes (solid grey line; original model) and correlated ligand noise across the whole receptor cluster (dashed grey line). For details, see Additional File 1.
