Figure 4From: Physical constraints on the establishment of intracellular spatial gradients in bacteriaBackground source and sink activities do not significantly perturb the R ∼ P gradient even for high rates. A) Schematic of localization of source and sink activities; the green and red shading represent the background activity. B) Mathematical modeling of the effects of background source and sink activities on the distributions of [R ∼ P]. (Inset) The ratio of [R ∼ P] between the two poles is not significantly affected by background source and sink rates.Back to article page
