    • +, log K = 0.5; under these experimental conditions 60% and <2% of the Ni(II) is initially in these two complexes, respectively.

    • GGH,exptl = -0.583; we suspect that the difference between this and the pH 9.1 value indicates that there are minor thermodynamic contributions from mixed Cu-GGH-Tris species, which we are unable to consider in our analysis.

    • 11; however, it is not clear whether deprotonation of the two amides of the N-terminal DTH-sequence upon Cu(II) binding was included in the analysis, and the report of a Scatchard plot for Cu(II) binding at pH 5.0 that is identical to those at pH 7.0 and 8.5 is at odds with potentiometric and spectroscopic data for Cu(II) binding to a number of XXH-sequences.

    • note
    • Optical data indicate a small difference in the Ni(II) ligand field of Ni-HGH, relative to that of Ni-GGH.
