Is Cu2+ in CuSO4 a competitive or non competitive inhibitor when it comes to inhibiting pectinase?

Answer 1

Sarah,

We cannot answer this without consulting the literature to see what others have found. You could do that just as well.

If you happen to be doing an experiment using Cu²⁺ as an inhibitor of pectinase, and you have some data, then you might want to present the data, and we could then tell you the nature of the inhibition.

If only the Km changes in the presence of Cu²⁺, then it would be a competitive inhibitor.

If only the Vmax changes in the presence of Cu²⁺, then it would be non-competitive inhibitor.

Does this help you?
