Table 1. Constants used for the quantitative model of Redβ behavior.

Constant	Value	Unit	Explanation
a dimer	(2.22 ± 1.28) ∙ 105	M−1	Association constant of β 1 + β 1 ⇆ β 2
a	(2.96 ± 0.28) ∙ 106	M−1	Association constant of β n + β 1 ⇆ β n+1, n ≥ 2
K d	(5.0 ± 0.2) ∙ 10−6	M	Dissociation constant of β 1 + ssDNA ⇆ ssDNA ⋅ β 1
K oligo	(3.4 ± 0.6) ∙ 10−1		Dissociation constant of Redβ protomers β unbound ⇆ β bound from ssDNA

Parameter ± standard error. Protomer: structural unit of a protein oligomer; a _dimer = a _{m = 1}, a = a _m>1, where m is the degree of oligomerization; see Eq 4. Note that the K _d is for a single binding site. The effective K _d depends on the ssDNA length and, here, is K _Epstein ≈ 240 nM.
