For the Metalloprotein Hemerythrin, the statement that is not true is: A. Unlike hemoglobin, most hemerythrins lack cooperative binding to oxygen

Is hemoglobin a metalloprotein?

The structure of hemoglobin. The heme cofactor, containing the metal iron, shown in green. Metalloprotein is a generic term for a protein that contains a metal ion cofactor. A large proportion of all proteins are part of this category.

How are metal ions coordinated in metalloproteins?

In metalloproteins, metal ions are usually coordinated by nitrogen, oxygen or sulfur centers belonging to amino acid residues of the protein. These donor groups are often provided by side-chains on the amino acid residues.

What is the function of metalloproteins?

Metalloproteins are widely distributed in nature and perform important biological functions, such as oxygen transport in invertebrates (hemerythrin, hemocyanin), iron storage and transport (ferritin, transferritin), and copper storage and transport (ceruloplasmin). The group includes numerous enzymes (for example, certain peptidases,…

Is myohemerythrin a monomeric protein?

Myohemerythrin is a monomeric O 2 -binding protein found in the muscles of marine invertebrates. Hemerythrin and myohemerythrin are essentially colorless when deoxygenated, but turn a violet-pink in the oxygenated state. Hemerythrin does not, as the name might suggest, contain a heme.

Abstract. Respiring organisms have evolved three principal oxygen transport proteins, hemoglobins, hemerythrins, and hemocyanins, that possess radically different polypeptide structures, subunit aggregates, and active site structures. Hemoglobins are by far the most widespread, occurring in all mammals and vertebrates, many invertebrates …
