Chemical biology: A degrading solution to pollution

J. Wade Harper1

Environmental pollutants such as dioxins affect human health. It now seems that dioxins exert their effect by forming atypical enzyme complexes that mediate the breakdown of steroid-hormone receptors.

Dioxins are some of the most prevalent and dangerous pollutants in the environment. They are generated as by-products of, among other things, rubbish incineration and industrial processes1, and act by disrupting the endocrine system.
