LITERATURE
Fe
-
non-heme iron enzyme, the enzyme could possess a non-heme ferric iron centre that is lost when the 20000 Da polypeptide is subjected to SDS-PAGE, but that can be reconstituted by addition of Fe3+ ions to the refolded enzyme
Fe2+
-
the enzyme is activated 6fold and 21fold by 0.01 mM and 0.1 mM ferrous ions, respectively
Iron
-
contains 3-5 nonhaem, non-iron-sulfur iron atoms as prosthetic groups, predominantly coordinated by carboxylate ligands
