EC 1.3.98.6     
Accepted name: AdoMet-dependent heme synthase
Reaction: Fe-coproporphyrin III + 2 S-adenosyl-L-methionine = protoheme + 2 CO2 + 2 5′-deoxyadenosine + 2 L-methionine
Other name(s): ahbD (gene name); SAM-dependent heme synthase
Systematic name: Fe-coproporphyrin III:S-adenosyl-L-methionine oxidoreductase (decarboxylating)
Comments: This radical AdoMet enzyme participates in a heme biosynthesis pathway found in archaea and sulfur-reducing bacteria. cf. EC 1.3.98.5, hydrogen peroxide-dependent heme synthase.
