magnesium chelatase activity

Known as: Mg-protoporphyrin IX chelatase activity, magnesium-chelatase activity, magnesium-protoporphyrin IX chelatase activity 
Catalysis of the reaction: ATP + H(2)O + Mg(2+) + protoporphyrin IX = ADP + 2 H(+) + magnesium protoporphyrin IX + phosphate. [EC:6.6.1.1, RHEA:13964…
