CommentThis HMM represents one of two ATPase subunits of the trimeric magnesium chelatase responsible for insertion of magnesium ion into protoporphyrin IX. This is an essential step in the biosynthesis of both chlorophyll and bacteriochlorophyll [1]. This subunit is found in green plants, photosynthetic algae, cyanobacteria and other photosynthetic bacteria. Unlike subunit I (TIGR02030), this subunit is not found in archaea.
