Metals/Ions Comment Organism Structure
Calcium a conserved calcium ion (calcium I) with octahedral coordination is present near the active site. A second calcium site with octahedral geometry, coordinated to propionates of hemes 3 and 4, and caged by a loop non-existent in the previous structures. The main role of this calcium may not be electrostatic but structural Desulfovibrio desulfuricans
