Biochem/physiol Actions
Oxygen transporter, NO scavenger
Hemoglobin is the most important respiratory protein of vertebrates by its ability to transport oxygen from the lungs to body tissues and to facilitate the return transport of carbon dioxide. The ferrous-ferric (Fe2+/Fe3+) balance is a physiological indicator of blood oxygenation. Deoxygenated hemoglobin accessorizes a feedback loop by reducing nitrite to nitric oxide (NO), a vasodilator which enhances blood flow to oxygen-deprived tissues. The fetal and adult hemoglobin from horse display differences in their affinity towards 2,3-diphosphoglycerate (2,3-DPG). Mutation in the globin gene is implicated in sickle cell anemia.
Disclaimer
Since native hemoglobin is readily oxidized in air, these preparations may be predominantly methemoglobin.
Application
Hemoglobin equine has been used as a standard protein:
- to test solid-film sampling methodology in Fourier transform infrared spectroscopy (FT-IR) for protein secondary structure determination
- in capillary reversed-phase liquid chromatography-tandem mass spectrometry (LC/MS/MS) post enzymatic digestion
- for quantification of hemoglobin content from the planktonic crustacean, Daphnia magna
General description
Hemoglobin is the major component of red blood cells and is responsible for their red color. Its normal concentration in erythrocytes is 34%. The structure of horse hemoglobin was elucidated first. It comprises heme (iron protoporphyrin IX group) and four polypeptide chains. The fetal and adult hemoglobin of horse are structurally identical.

The physiological significance of the position and shape of the oxygen equilibrium curve (OEC) of horse hemoglobin (Hb) is considered from the viewpoint of oxygen (O2) transport efficiency and the effectiveness of the Bohr effect. In horse fetal and maternal

Centrosomes are essential organelles that organize the microtubule cytoskeleton during interphase and mitosis. Centrosomes are assembled from tens to hundreds of proteins, but how these proteins are organized into functional microtubule nucleating and organizing centers is not yet clear. An

In this report, we describe an approach for identification and relative quantitation of individual proteins within mixtures using LC/MS/MS analysis of protein digests. First, the proteins are automatically identified by correlating the tandem mass spectra with peptide sequences from a
