Hemoprotein
From Wikipedia, the free encyclopedia
A hemoprotein (also haemoprotein), or heme protein, is a metalloprotein containing a heme prosthetic group, either covalently or noncovalently bound to the protein itself. The iron in the heme is capable of undergoing oxidation and reduction (usually to +2 and +3, though stabilized ferryl [Fe+4] compounds are well known in the peroxidases).
[edit] Roles
Hemoproteins have diverse biological functions including:
- transport
- hemoglobin
- myoglobin
- neuroglobin
- cytoglobin
- leghemoglobin
- catalysis
- peroxidases
- cytochrome c oxidase
- ligninases
- active membrane transport
- electron transfer
