MetaCyc Compound Class: heme d

Superclasses: a macrocycle a porphyrin heme
an organometallic compound

Summary:
'heme' is usually understood as any tetrapyrrolic chelate of iron. The terms 'ferroheme' and 'ferriheme' refer to the Fe(II) and Fe(III) oxidation states in heme (even though Fe(IV) is found as a catalytic intermediate in some systems).

The term "heme d" has been used to describe the heme group of cytochromes d. However, the various alternative forms for hemes found in cytochromes d preclude such a simple classification.
