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>. | 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>.
