1 These findings are interpreted assuming that in presence of Ca2+ the three subunits forming the native S-100 protein have two cysteine residues exposed to the solvent but mismatched to form disulfides while in presence of K+ the sulphydryl groups are in a less accessible position to Nbs2 but suitable for S-S bond formation.
