Hydrogen/deuterium (H/D) exchange or chemical cross-linking by soluble carbodiimide (EDC) was employed in combination with high-resolution mass spectrometry (MS) to extend our knowledge about contact surface regions involved in the well-characterized model of interaction between two molecules of human 14-3-3 zeta regulatory protein. The H/D exchange experiment provided low resolution mapping of interaction in the homodimeric 14-3-3 zeta complex. A lower level of deuteration, suggesting structural protection, of two sequential segments has been demonstrated for dimeric 14-3-3 zeta wild type relative to the monomeric mutant 14-3-3 zeta S58D. The N-terminal sequence (the first 27 residues) from one subunit interacts with region alpha C' and alpha D'-helices (residues 45-98) of the other molecule across the dimer interface
