CC ChEBI:CHEBI:60492, ChEBI:CHEBI:456216; EC=6.6.1.1;
CC Evidence={ECO:0000256|ARBA:ARBA00001499,
CC ECO:0000256|RuleBase:RU362087};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; bacteriochlorophyll
CC biosynthesis. {ECO:0000256|RuleBase:RU362087}.
CC -!- SIMILARITY: Belongs to the Mg-chelatase subunits D/I family.
