Hagfish hemoglobins: structure, function, and oxygen-linked association.
Cyclostomes, hagfishes and lampreys, contain hemoglobins that are monomeric when oxygenated and polymerize to dimers or tetramers when deoxygenated. The three major hemoglobin components (HbI, HbII, and HbIII) from the hagfish Myxine glutinosa have been characterized and compared with lamprey Petromyzon marinus HbV, whose x-ray crystal structure has been solved in the deoxygenated, dimeric stat...
متن کاملUnderstanding Hagfish Embryology
zoologists, especially in the context of vertebrate evolution. Embryological information on these animals is now also needed in the field of evolutionary developmentaT biology {Evo-Devo), as it is expected to provide hints about the origin of vertebrate traits, whether the hagfishes are an inor outgroup of vertebrates,This review summarizes the importance of hagtish embryology from a phylogenet...
متن کاملHagfish pump some iron
Along with other nutrients, animals need trace metals to function. Iron, the oxygenbinding component in the blood pigment hemoglobin, is a critical trace metal and is usually absorbed through the gut. Mammals can alter iron metabolism in order to meet oxygen demand during periods of low environmental oxygen – hypoxia. However, it was unknown whether hagfish – a much more primitive group of anim...
متن کاملPlant hemoglobins
Hbs are ubiquitous proteins in most organisms, including bacteria, protozoans, fungi, plants, and animals (Vinogradov et al., 1993; Bolognesi et al., 1997). The known and predicted roles of Hbs in each organism encompass functions that include the reversible binding of gaseous ligands and the ability to bind other cellular molecules.

متن کاملVariable lymphocyte receptors in hagfish.
A previously uncharacterized type of variable lymphocyte receptors (VLR) was identified recently in the Sea lamprey. This jawless vertebrate generates an extensive VLR repertoire through differential insertion of neighboring diverse leucine-rich repeat (LRR) cassettes into an incomplete germ-line VLR gene. We report here VLR homologs from two additional lamprey species and the presence of two t...
