The active site for Bd Oxidase in Geobacillus thermodenitrificans is located in subunit Cyd A. The site consists of three iron hemes that are held together in a rigid triangular arrangement (green link) due to van der wals interactions. The length between each heme's central iron is relatively constant which serves to shuttle protons and electrons from one heme to another efficiently.

This is a sample scene created with SAT to color by Group, and another to make a transparent representation of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes. Scene created by Carson: Residues 30-65[1].
