 84-227 1.33e-16

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.

 88-216 2.85e-03

Vitreoscilla stercoraria hemoglobin and related proteins; single-domain globins; VtHb is homodimeric, and may both transport oxygen to terminal respiratory oxidases, and provide resistance to nitrosative stress. It has medium oxygen affinity and displays cooperative ligand-binding properties. VHb has biotechnological application, its expression in heterologous hosts (bacteria and plants) has improved growth and productivity under microaerobic conditions. Another member of this subfamily Campylobacter jejuni hemoglobin (Cgb) is monomeric, and plays a role in detoxifying NO. Along with a truncated globin Ctb, it is up-regulated by the transcription factor NssR in response to nitrosative stress.

 149-217 4.34e-03

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.

 147-217 5.93e-03

Globin domain of uncharacterized oxidoreductases containing a FAD/NADH binding domain; This subfamily is composed of uncharacterized proteins containing an N-terminal myoglobin-like (M family globin) domain and a C-terminal oxygenase reductase FAD/NADH binding domain belonging to the ferredoxin reductase (FNR) family and is usually part of multi-component bacterial oxygenases which oxidize hydrocarbons using oxygen as the oxidant. The domain architecture of this subfamily is similar to flavohemoglobins, which function primarily as nitric oxide dioxygenases (NODs, EC 1.14.12.17), converting NO and O2 to inert NO3- (nitrate). 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.
