structure in presence of iron. Only a single iron ion is found in the active site, coordinated in a square pyramidal fashion by two amino acid residues, His183 and Glu264, and three water molecules. This iron ion is not present in the structure of a His183Ala modified ferrochelatase. Insertion of a metal ion into protoporphyrin IX by ferrochelatase occurs from a metal binding site represented by His183 and Glu264 | Bacillus subtilis |
