Structural characterization of an Ascaris myoglobin - PubMed
1994年12月2日 · Evolutionary analysis of the nematode globins suggests that the monodomain myoglobin-like molecules and the two-domain hemoglobin-like molecules diverged about 500 million years ago, well before the divergence of the ascarid genera Ascaris and Pseudoterranova.
Structural characterization of an Ascaris myoglobin.
Evolutionary analysis of the nematode globins suggests that the monodomain myoglobin-like molecules and the two-domain hemoglobin-like molecules diverged about 500 million years ago, well before the divergence of the ascarid genera Ascaris and Pseudoterranova.
Functions of Cytoplasmic Hemoglobins and Myohemerythrin
Only hemerythrin and hemoglobin occur within tissue cells. This essay addresses the functions of myohemerythrin (muscle hemerythrin) and cytoplasmic hemoglobin in muscles, nerves, gills, and other tissues of invertebrates. Download to read the full chapter text.
known for over 100 years that parasitic nematodes contain globins, but recent molecular investigations are only now beginning to shed some light on their curious properties. Mark Blaxter here describes the diversity of the different globins found in …
Molecular characterization of Clonorchis sinensis secretory myoglobin ...
2014年5月29日 · Myoglobin, a hemoprotein, is present in high concentrations in trematodes and ESPs. To further understand the biological function of Cs Mb and its putative roles in the interactions of C. sinensis with its host, we explored the …
Ever Surprising Nematode Globins - SpringerLink
Nematodes express pseudocoelomic, body wall and cuticle globin isoforms. All globin isoforms display the major determinants of the globin fold and a B10Tyr/E7Gln residue pair, which is a signature of high oxygen affinity. The hitherto studied pseudocoelomic globins are octamers of covalently linked didomain globin chains.
Ascaris suum NADH-methemo(myo)globin reductase systems
We reported previously that Ascaris suum cytochrome b5, specifically expressed in this nematode at the adult stage and dually localized in extracellular perienteric fluid and hypodermis, is involved in both perienteric NADH-methemoglobin and cytosolic NADH-metmyoglobin reduction, where cytochrome b5 ….

2009年5月1日 · We reported previously that Ascaris suum cytochrome b5, specifically expressed in this nematode at the adult stage and dually localized in extracellular perienteric fluid and hypodermis, is...
Ascaris Haemoglobin: New Tricks for an Old Protein
2000年4月1日 · Nematode secreted haemoglobins have unusually high affinity for oxygen and possess nitric oxide deoxygenase, and catalase activity thought to be important in protection against host immune ...
Kinetics of ligand binding to Pseudoterranova decipiens and …
1993年8月15日 · The kinetics of binding of O2, CO, and NO to the octameric, two-domain hemoglobins of the parasitic nematodes Pseudoterranova decipiens and Ascaris suum were determined on nanosecond and picosecond time scales using flash photolysis. The two nematode hemoglobins have very similar kinetic properties. ….
