Relations between structural modifiactions and SOD-like activity of four branched Cu II-
metallopeptides based on l-2, 3-diaminopropionic acid are reported. The IC 50 values
(McCord–Fridovich method) illustrate that enhanced SOD-like activity is warranted by
exclusive N-terminal His localization that surmounts the driving force by the Cu II/I formal
potential.
