Metals/Ions

Metals/Ions Comment Organism Structure
Mg2+ removal of Mg2+ from the protochlorophyllide leads to inactivity of the compound as a substrate, activity can be restored by replacing the magnesium with zinc, whereas nickel, copper or cobalt fail to restore substrate activity Hordeum vulgare
Zn2+ removal of Mg2+ from the protochlorophyllide leads to inactivity of the compound as a substrate, activity can be restored by replacing the magnesium with zinc, whereas nickel, copper or cobalt fail to restore substrate activity Hordeum vulgare
