Abstract excerpt
Magnesium (Mg) chelatase is a heterotrimeric enzyme complex that catalyzes a key regulatory and enzymatic reaction in chlorophyll biosynthesis, the insertion of Mg(2+) into protoporphyrin IX. Studies of the enzyme complex reconstituted in vitro have shown that all three of its subunits, CHL I, CHL D, and CHL H, are required for enzymatic activity. However, a new T-DNA knockout mutant of the chlorina locus, ch42-3...
