Enzymeregulation
... Suppose supply of E in cell increases (e.g. eat a meal rich in E). How to shut down synthesis of E? Cell's answer: Enzyme 1 is reversibly inhibited by E. Note that E is not the substrate, and chemically so different that it cannot bind to active site. How does E shut down Enzyme 1? Enz 1 is a specia ...
