Protein Classification

hemoglobin beta-like protein( domain architecture ID 10172378)

hemoglobin beta-like protein is either one of gamma, delta, epsilon, or related Hb subunits. Hb is the oxygen transport protein of erythrocytes. It is an allosterically modulated heterotetramer. Hemoglobin A (HbA) is the most common Hb in adult humans, and is formed from two alpha-chains and two beta-chains (alpha2beta2). An equilibrium exists between deoxygenated/unliganded/T(tense state) Hb having low oxygen affinity, and oxygenated /liganded/R(relaxed state) Hb having a high oxygen affinity. Various endogenous heterotropic effectors bind Hb to modulate its oxygen affinity and cooperative behavior, e.g. hydrogen ions, chloride ions, carbon dioxide and 2,3-bisphosphoglycerate. Hb is also an allosterically regulated nitrite reductase; the plasma nitrite anion may be activated by hemoglobin in areas of hypoxia to bring about vasodilation.

Hb is also an allosterically regulated nitrite reductase; the plasma nitrite anion may be activated by hemoglobin in areas of hypoxia to bring about vasodilation. Other Hb types are: HbA2 (alpha2delta2) which in normal individuals, is naturally expressed at a low level; Hb Portland-1 (zeta2gamma2), Hb Gower-1 (zeta2epsilon2), and Hb Gower-2 (alpha2epsilon2), which are Hbs present during the embryonic period; and fetal hemoglobin (HbF, alpha2gamma2), the primary hemoglobin throughout most of gestation. These Hbs types have differences in O2 affinity and in their interactions with allosteric effectors.

Cytoglobin and related globins; Cygb is a hexacoordinated heme-containing protein, able to bind O2, NO and carbon monoxide. It has both nitric oxide dioxygenase and lipid peroxidase activities, and potentially participates in the maintenance of normal phenotype by implementing a homeostatic effect, to counteract stress conditions imposed on a cell. Cygb is implicated in multiple human pathologies: it is up-regulated in fibrosis and neurodegenerative disorders, and down-regulated in multiple cancer types, and may have a tumor suppressor role. It is expressed ubiquitously across a broad range of vertebrate organs including liver, heart, brain, lung, retina, and gut. In the human brain, it was detected at high levels in the habenula, hypothalamus, thalamus, hippocampus and pontine tegmental nuclei, detected at a low level in the cerebral cortex, and undetected in the cerebellar cortex.

myoglobin-like; M family globin domain; This family includes chimeric (FHbs/flavohemoglobins) and single-domain globins: FHbs, Ngbs/neuroglobins, Cygb/cytoglobins, GbE/avian eye specific globin E, GbX/globin X, amphibian GbY/globin Y, Mb/myoglobin, HbA/hemoglobin-alpha, HbB/hemoglobin-beta, SDgbs/single-domain globins related to FHbs, and Adgb/androglobin. The M family exhibits the canonical secondary structure of hemoglobins, a 3-over-3 alpha-helical sandwich structure (3/3 Mb-fold), built by eight alpha-helical segments (named A through H). In Adgbs, the globin domain is split into two: helices C-H are followed by helices A-B and the two parts are separated by the IQ motif. Although rearranged, the globin domain of most Adgbs contains a number of conserved residues which play critical roles in heme-coordination and gas ligand binding. Adgbs have been omitted from this A-H helix cd.

 7-147 2.12e-09

Animal Myoglobins; Myoglobin (Mb) is a monomeric pentacoordinate heme-bound globin protein whose expression has long been considered limited to cardiomyocytes and striated skeletal muscle cell, however it has recently been found localized in a wide variety of tissues including smooth muscle cells. As a physiological catalyst, it can modulate reactive oxygen species levels, facilitate oxygen diffusion within the cell, and scavenge or generate NO depending on oxygen tensions within the cell. Through its NO dioxygenase and nitrite reductase activities, Mb regulates mitochondrial function in energy-demanding tissues.

Hell's gate globin I (HGbI) from Methylacidophilum infernorum and related proteins; HGbI is a single-domain heme-containing protein isolated from Methylacidiphilum infernorum, an aerobic acidophilic and thermophilic methanotroph. M. infernorum grows optimally at pH 2.0 and 60C and its home is New Zealand's Hell's Gate geothermal park. The physiological role of HGbI has yet to be determined. It has an extremely strong resistance to auto-oxidation, and has fast oxygen-binding/slow release characteristics. Its CO on-rate is comparable to the O2 on-rate, and it is able to bind acetate with high affinity in the ferric state. The coordination of the heme iron changes in the ferrous form from pentacoordinate at low pH to predominantly hexacoordinate at high pH; in the ferric form, it is predominantly hexacoordinate at all pH.

 5-134 2.83e-04

Globin domain of fungal flavohemoglobin; FlavoHbs function primarily as nitric oxide dioxygenases (NODs, EC 1.14.12.17), converting NO and O2 to inert NO3- (nitrate). They have an N-terminal globin domain and a C-terminal ferredoxin reductase-like NAD- and FAD-binding domain, and use the reducing power of cellular NAD(P)H to drive regeneration of the ferrous heme. They protect from nitrosative stress (the broad range of cellular toxicities caused by NO), and modulate NO signaling pathways. NO scavenging by flavoHb attenuates the expression of the nitrosative stress response, affects the swarming behavior of Escherichia coli, and maintains squid-Vibrio fischeri and Medicago truncatula-Sinorhizobium meliloti symbioses. FlavoHb expression affects Aspergillus nidulans sexual development and mycotoxin production, and Dictyostelium discoideum development.

Neuroglobins; The Ngb described in this subfamily is a hexacoordinated heme globin chiefly expressed in neurons of the brain and retina. In the human brain, it is highly expressed in the hypothalamus, amygdala, and in the pontine tegmental nuclei. It affords protection of brain neurons from ischemia and hypoxia. In rats, it plays a role in the neuroprotection of limb ischemic preconditioning (LIP). It plays roles as: a sensor of oxygen levels; a store or reservoir for oxygen; a facilitator for oxygen transport; a regulator of ROS; and a scavenger of nitric oxide. It also functions in the protection against apoptosis and in sleep regulation. This subgroup contains Ngb from mammalian and non-mammalian vertebrates, including fish, amphibians and reptiles; the functionally pentacoordinated acoelomorph Symsagittifera roscoffensis Ngb does not belong to this subgroup.
