ATP + protoporphyrin IX + Mg2+ + H2O Synechocystis sp. magnesium chelatase H subunit markedly enhances magnesium protoporphyrin methyltransferase catalysis by accelerating the formation and breakdown of the catalytic intermediate, providing a kinetic link between the first two reactions of chlorophyll biosynthesis with the signalling molecule magnesium protoporphyrin as the common factor ADP + phosphate + Mg-protoporphyrin IX + H+
