Nitric oxide: an antiparasitic molecule of invertebrates.
Since Furchgott, Ignarro and Murad won the Nobel prize in 1998 for their work on the role of nitric oxide (NO) as a signaling molecule, many reports have shown the seemingly limitless range of body functions controlled by this compound. In vertebrates, the role of NO as a defense against infection caused by viruses, bacteria, and protozoan and metazoan parasites has been known for several years...
متن کاملHemoglobin-mediated nitric oxide signaling.
The rate that hemoglobin reacts with nitric oxide (NO) is limited by how fast NO can diffuse into the heme pocket. The reaction is as fast as any ligand/protein reaction can be and the result, when hemoglobin is in its oxygenated form, is formation of nitrate in what is known as the dioxygenation reaction. As nitrate, at the concentrations made through the dioxygenation reaction, is biologicall...
متن کاملHemoglobin: A Nitric-Oxide Dioxygenase
Members of the hemoglobin superfamily efficiently catalyze nitric-oxide dioxygenation, and when paired with native electron donors, function as NO dioxygenases (NODs). Indeed, the NOD function has emerged as a more common and ancient function than the well-known role in O2 transport-storage. Novel hemoglobins possessing a NOD function continue to be discovered in diverse life forms. Unique hemo...
متن کاملCorrelation between Nitric oxide (NO) & Asymmetric dimethylargininie (ADMA) Hemoglobin
73/ Spring summer 2010, Vol.4, No. 1 Medical Laboratory Journal Correlation between Nitric oxide (NO) & Asymmetric dimethylargininie (ADMA) Hemoglobin Concentration in sickle cell patients Abstract Background and objectives: The importance of Nitric oxide (NO) and Asymmetric dimethylargininie (ADMA) in pathophysiology of Sickle cell disease (SCD) is being increasingly clarified. Since very few ...
متن کاملParamagnetic resonance study of Nitric Oxide hemoglobin.
The electron paramagnetic resonance absorption of nitric oxide hemoglobin was observed as a possible model system for oxyhemoglobin. The electron paramagnetic resonance spectrum showed three g factors indicating a rhombic symmetry around the paramagnetic center. By use of 15N0, the unpaired electron was found very little associated with NO nitrogen, in contrast to what has been customarily assu...
