Myohemerythrin
WebHemerythrins have been isolated from muscle, the vascular system, and the coelom of the sipunculid Dendrostomum pyroides. Muscle hemerythrin (myohemerythrin), vascular hemerythrin, and coelomic hemerythrin have been purified by ammonium sulfate precipitation and have been partially characterized.

WebMyohemerythrin, like myoglobin, stores oxygen in the muscles of many marine invertebrates ("Myohemerythrin" website). The two iron atoms are responsible for binding oxygen. WebThe chemistry of antibody recognition was studied by mapping the antigenicity of the protein myohemerythrin with peptide homologs of the protein sequence. The results suggest that the entire protein surface is antigenic, but the probability of there being antibodies to a given site is influenced by local stereochemistry.
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. See more Hemerythrin (also spelled haemerythrin; Ancient Greek: αἷμα, romanized: haîma, lit. 'blood', Ancient Greek: ἐρυθρός, romanized: erythrós, lit.
