General annotation (Comments)

Function

Involved in bacteriochlorophyll biosynthesis; introduces a magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX.

Catalytic activity

ATP + protoporphyrin IX + Mg2+ + H2O = ADP + phosphate + Mg-protoporphyrin IX + 2 H+.

Pathway

Porphyrin biosynthesis; bacteriochlorophyll biosynthesis.

Sequence similarities

Belongs to the Mg-chelatase subunits D/I family.
