CC -!- ACTIVITY REGULATION: Redox regulation; active in reducing conditions,
CC inactive in oxidizing conditions. {ECO:0000256|RuleBase:RU362087}.
CC -!- PATHWAY: Porphyrin-containing compound metabolism; chlorophyll
CC biosynthesis. {ECO:0000256|ARBA:ARBA00005173,
CC ECO:0000256|RuleBase:RU362087}.
CC -!- SUBUNIT: The magnesium chelatase complex is a heterotrimer consisting
CC of subunits CHLI, CHLD, AND CHLH. {ECO:0000256|RuleBase:RU362087}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast
CC {ECO:0000256|RuleBase:RU362087}.
CC -!- SIMILARITY: Belongs to the Mg-chelatase subunits D/I family.
