CD47 also known as integrin associated protein is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 and signal-regulatory protein alpha. 3D cartoon and Gaussian surface models, chain id color scheme, based on PDB 2jjt, white background

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.
