Comparison of ParM filament polymerization rates and plasmid segregation rates

	ParM in vitro	ParM in vivo	Plasmid segregation
Polymerization rate     (nm/s)	58 ± 6	46 ± 17	52 ± 17
Depolymerization rate     (nm/s)	157 ± 49	248 ± 73	NA

NA, not applicable. Averages ± SD. ParM rates in vitro are from Garner et al. (2004). ParM rates in vivo were measured from data such as those shown in Fig. 2. Plasmid segregation rates were measured from clear segregation events such as those seen in Fig. 1 (E and F). ParM polymerization, n = 22; ParM depolymerization, n = 9; plasmid segregation, n = 22.
