Table 1. Model Parameters.

Parameter	Brief description	Value	Source
$k_a$	Association rate to the nucleoid of cytosolic ParA	0.19 s–1	As Surovtsev et al., 2016a. Based on in vitro measurement from Vecchiarelli et al., 2010. Results in 95% ParA nucleoid association in the absence of a plasmid.

$k_h$	Tether dissociation due to plasmid stimulated hydrolysis of ParA	0.01–3 s–1	Sweeped over in this study.
$D_p$	Diffusion coefficient of the plasmid	3x10–3 μm2s–1	As Surovtsev et al., 2016a. Based on MSD of a Δpar plasmid.
$D_h$	Diffusion coefficient of ParA home position on the nucleoid	3.22x10–4 to 0.29 μm2s–1	Sweeped over in this study.
$D_A$	Diffusion coefficient of DNA-bound ParA due to chromosomal fluctuations	0.01 μm2s–1	As Surovtsev et al., 2016a; Based on Javer et al., 2014 and Weber et al., 2010.
