This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.

The tetrapyrrole in siroheme is heavily negatively charged because of the 8 acetyl and propionyl carboxylates at the corners of the siroheme and it interacts with <scene name='91/915831/Cv/6'>residues of subunits A and B</scene>. Five of these residues are positively charged <scene name='91/915831/Cv/7'>Arg and Lys residues</scene>.
