One is heme iron protein, such as hemoglobin, myoglobin, xanthine oxidases, cytochromes, etc. These proteins are those in which iron atoms are bound to porphyrin. The other class is non-heme iron protein. One of this is the iron-sulfur protein, in which iron atoms are bound to sulfur-containing ligands.展开更多
文摘There are two classes of proteins containing iron in the organism. One is heme iron protein, such as hemoglobin, myoglobin, xanthine oxidases, cytochromes, etc. These proteins are those in which iron atoms are bound to porphyrin. The other class is non-heme iron protein. One of this is the iron-sulfur protein, in which iron atoms are bound to sulfur-containing ligands.
