     The only thing I can come up with in answer to your question is that 
copper could affect the concentration of hydrogen peroxide in solution.  
Catalase uses hydrogen peroxide as a substrate.  Hydrogen peroxide is 
decomposed in the presence of metal ions such as copper.  Thus, the 
catalytic rate could be reduced by the effect of copper scavenging the 
enzyme's substrate.
