A comparison of copper binding properties, copper exchange rate and redox potential between two similar naturally occurring copper-binding peptides GHK and DAHK shows that even though both bind copper in stoichiometry at a ratio of 1:1, the exchange rate of copper between DAHK peptides is very slow, while the exchange rate between GHK peptides is much faster
