His-ΔNarG 0,77 0,72
His-ΔFnBPA 5,24 × 10 -6 0,31
His-ΔEbh 0,02 1,25 × 10 -6
His-ΔCoa < 0 1,80 × 10 -7
His-ΔPurK 4,43 × 10 -7 5,39 × 10 -6
His-ΔUsp 0,35 6,45 × 10 -6
His-ΔPBP 0,36 0,13
  1. * the steady state affinity constants (KD) of the seven analytes tested are shown in molar concentrations; values shown in bold indicate high affinity for the indicated ligand (Fn or Fg).
  2. † affinity was not measurable since all values were negative
