This model represents the H subunit of the magnesium chelatase complex responsible for magnesium insertion into the protoporphyrin IX ring in the biosynthesis of both chlorophyll and bacteriochlorophyll. In chlorophyll-utilizing species this gene is known as ChlH while in bacteriochlorophyll-utilizing spoecies it is called BchH. Subunit H is the largest (~140kDa) of the three subunits (the others being BchD/ChlD and BchI/ChlI) and is known to bind protoporphyrin IX. Subunit H is homologous to the CobN subunit of cobaltochelatase and by anology with that enzyme subunit H is believed to also bind the magnesium ion which is inserted into the ring. In conjunction with the hydrolysis of ATP by subunits I and D a conformation change is believed to happen in subunit H causing the magnesium ion insertion into the distorted protoporphyrin ring.

This family contains a domain common to the cobN protein and to magnesium protoporphyrin chelatase. CobN is implicated in the conversion of hydrogenobyrinic acid a c-diamide to cobyrinic acid. Magnesium protoporphyrin chelatase is involved in chlorophyll biosynthesis.

Cobaltochelatase is a complex enzyme that catalyzes the insertion of cobalt into hydrogenobyrinic acid a c-diamide resulting in cobyrinic acid as demonstrated for Pseudomonas denitrificans. This is an essential step in the bacterial synthesis of cobalamine (B12). The insertion of cobalt requires a complex composed of three polypeptides cobN cobS and cobT. Also included in this family are protoporphyrin IX magnesium chelatases involved in the synthesis of chlorophyll and bacteriochlorophyll specifically the large (chlH or bchH) subunits.They are thought to bind both the protoporphyrin and the magnesium ion. Hydrolysis of ATP by the smaller subunits in the complex may trigger a conformational change that results in the insertion of the ion into the protoporphyrin scaffold. Cryo electron microscopy studies have suggested that a distinct bchH C-terminal domain may bind tightly to the N-terminal domain upon substrate binding requiring a substantial conformational change of the bchH subunit. It has also been suggested that chlH of higher plants binds abscisic acid via a C-terminal domain and plays a role in abscisic acid signaling and that the protein spans the chloroplast envelope with the C-terminus exposed to the cytosol.
