Hi guys first post here, hopefully of many!
Pooled data from a FluroMetPlate assay testing the inhibitory effects of Mercury, Zinc, Cadmium and Copper on Beta-galactosidase has shown up (what I think to be) some strange results. Although all of the metals are toxic to the enzyme at high enough concentrations, zinc and cadmium actually increased enzyme activity at very low concentrations.
My literature search has proven fruitless but I could just be looking in the wrong places. Is the data to blame? or is there a painfully obvious answer that is just eluding me? any research for me to reference would also be much appreciated, or a point in the right direction!
