Dependence of the monomer and oligomers of FH and SCR-6/8 on zinc concentrations. (a) The values from c(s) integrations correspond to the averages obtained at 50,000 rpm and 60,000 rpm. The oligomer data were fitted to a two-parameter power function, y = a × (1 + x)^b, and the monomer data were fitted to the function f = y0 + a × x^b. Oligomers are denoted by filled symbols, and monomers are denoted by open symbols for four experiments with two FH Tyr402 (026II, 022LM, blue, ●, ○, ▲, Δ) and two FH His402 (027BA, 032KO, red, ●, ○, ▲, Δ) allotypes. (b) The proportions of monomer of the Tyr402 (blue) and His402 (red) allotypes of SCR-6/8 are shown.
