Thanks a lot for the quick and informative reply. I believe that some bizzare results are due to experimental variation as you've mentioned previously. However, I'm not sure about how copper II ions are able to displace Fe III ions from the heme group in the centre of a porphyrin ring of catalase when copper is lower down in the reactivity series relative to iron. Copper ions inhibits protein activity by disrupting disuphide bonds. So inhibition of catalase by copper ions can take two forms? One whereby it displaces iron III ions in the active site and two by disrupting disulphide bonds or does the former lead to the latter? Thanks a lot!!!
