Biology

Superoxide dismutase is a very unique protein. It is the onlyprotein that can catalyze faster than the rate of diffusion, whichis usually a limiting rate for proteins since you cannot catalyzesomething faster than the amount of time it takes for yoursubstrate to arrive at the active site. However, superoxidedismutase is able to do this. If you look at a diagram ofsuperoxide dismutase, you will find a large cluster of basic aminoacids surrounding the active site where the substrate binds. First,state the purpose of superoxide dismutase and what its substrateis. Then discuss how you think superoxide dismutase is able to havea kcat/Km that is faster than the diffusion limit.
