How many subunits does myoglobin have
WebThis effect was first noted in the EPR spectrum of Fe(II)NO myoglobin by Morse and Chan22. As illustrated in Fig. 6, once the sample temperature exceeds115K, there appears to be sufficiently rapid and unrestricted motion of the nitrite ligand that the spectra of both of the metHb:NO2− species no longer exhibit g-anisotropy.

Myoglobin belongs to the globin superfamily of proteins, and as with other globins, consists of eight alpha helices connected by loops. Myoglobin contains 153 amino acids. Myoglobin contains a porphyrin ring with an iron at its center. A proximal histidine group (His-93) is attached directly to iron, and a … Meer weergeven Myoglobin (symbol Mb or MB) is an iron- and oxygen-binding protein found in the cardiac and skeletal muscle tissue of vertebrates in general and in almost all mammals. Myoglobin is distantly related to hemoglobin. … Meer weergeven Myoglobin contains hemes, pigments responsible for the colour of red meat. The colour that meat takes is partly determined by the degree of oxidation of the myoglobin. … Meer weergeven Many models of myoglobin have been synthesized as part of a broad interest in transition metal dioxygen complexes. A well known example is the picket fence porphyrin, which consists of a ferrous complex of a sterically bulky derivative of Meer weergeven • Collman JP, Boulatov R, Sunderland CJ, Fu L (Feb 2004).
