Characterization of the magnesium chelatase from Thermosynechococcus elongatus

The first committed step in chlorophyll biosynthesis is catalysed by magnesium chelatase (E.C. 6.6.1.1), which uses the free energy of ATP hydrolysis to insert an Mg(2+) ion into the ring of protoporphyrin IX. We have characterized magnesium chelatase from the thermophilic cyanobacterium Thermosynec...
