ATPase activity associated with the magnesium-protoporphyrin IX chelatase enzyme of Synechocystis PCC6803: evidence for ATP hydrolysis during Mg2+ insertion, and the MgATP-dependent interaction of the ChlI and ChlD subunits.

Insertion of Mg2+ into protoporphyrin IX catalysed by the three-subunit enzyme magnesium-protoporphyrin IX chelatase (Mg chelatase) is thought to be a two-step reaction, consisting of activation followed by Mg2+ chelation. The activation step requires ATP and two of the subunits, ChlI and ChlD (I an...
