Hemerythrin typically exists as a homooctamer or heterooctamer composed of α- and β-type subunits of 13–14 kDa each, although some species have dimeric, trimeric and tetrameric hemerythrins. Each subunit has a four-α-helix fold binding a binuclear iron centre. Because of its size hemerythrin is usually … See more Hemerythrin (also spelled haemerythrin; Ancient Greek: αἷμα, romanized: haîma, lit. 'blood', Ancient Greek: ἐρυθρός, romanized: erythrós, lit. 'red') is an oligomeric protein responsible for oxygen (O2) transport in the marine invertebrate See more The mechanism of dioxygen binding is unusual. Most O2 carriers operate via formation of dioxygen complexes, but hemerythrin holds the O2 as a hydroperoxide (HO2, or -OOH ). The site that binds O2 consists of a pair of iron centres. The iron … See more • 1HMD - PDB structure of deoxyhemerythrin Themiste dyscrita (sipunculid worm) • 1HMO – PDB structure of oxyhemerythrin from Themiste … See more The hemerythrin/HHE cation-binding domain occurs as a duplicated domain in hemerythrins, myohemerythrins and related proteins. … See more • Karlsen, O.A., Ramsevik, L., Bruseth, L.J., Larsen, Ø., Brenner, A., Berven, F.S., Jensen, H.B. and Lillehaug, J.R.

It has been found that in some α-helical regions of the protein, about every third or fourth amino acid residue is a hydrophobic one. Suggest a reason for this finding, based on the structure you found.

WebHemeritrina. Hemeritrina, (en anglès: Hemerythrin o haemerythrin ); del grec αίμα = sang i ερυθρός = roig) és una proteïna oligomèrica responsable del transport de l' oxigen (O₂) en els invertebrats marins dels embrancaments dels sipuncúlids, priapúlids, braquiopodes, i del gènere de cusc annèlids, Magelona. WebIteration of the HHE family found it to be related to Hemerythrin. It also demonstrated that what has been described as a single domain in fact consists of two cation binding domains. Members of this family occur all across nature and are involved in a variety of processes. For instance, in Nereis diversicolor hemerythrin binds Cadmium so as to ... WebAbstract. The absorption and circular dichroic spectra of hemerythrin in its deoxy, oxy, and several met states have been interpreted by comparison with those of several model systems and correlated with Mössbauer and magnetic data. The properties of the methemerythrin complexes are consistent with the presence of a dimeric pair of high spin ... installing flooring over carpet
