Summary of values obtained from electrochemal, kinetic, and statistical analysis of metallopeptides and their in vitro DNA cleavage activity.
Parameter | p1-Cu | p3-Cu | Cu2+ |
---|---|---|---|
E° vs NHEa (V) | 0.990 | 0.972 | Nd |
kcleavage (× 10−3 min−1) | 6.3 ± 0.5 | 18.2 ± 0.7 | 22.1 ± 0.6 |
n1/n2 | 34 | 27 | 27 |
The standard potential was referenced to H+/H2 couple, the normal hydrogen electrode (NHE).
