. "This family contains a domain common to the cobN protein and tomagnesium protoporphyrin chelatase. CobN is implicated in the conversion of hydrogenobyrinic acid a,c-diamide to cobyrinic acid [1]. Magnesium protoporphyrin chelatase is involved in chlorophyll biosynthesis [2]. " . "CobN-Mg_chel" . "CobN/Magnesium Chelatase" . "Mian N, Bateman A, Griffiths-Jones SR" .
