Bacterial dehalogenases remove halogen atoms from organic compounds. The one shown here is a reductive dehalogenase from PDB entry 4ur0. It uses a cobamide cofactor (orange) and iron-sulfur clusters to reduce the substrate. Dehalogenases may be used as a way to clean up areas polluted with halogenated compounds.

A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
