Abstract In previous studies, particularly of primates, a high degree of concordance was obtained between an evolutionary pattern based on comparative anatomy and another based on a reconstruction of the possible pathway of evolution of the myoglobin molecule.

Cellular and Molecular Life Sciences CMLS, 1998
The distribution, physiological function, amino acid sequence and gene structure of myoglobin and myoglobin-like proteins from various taxa are summarized, and their evolution is discussed. Although it has long been thought that all haemoglobins and myoglobins have evolved from a common ancestral gene, the knowledge presently accumulated about the ...

Summary.Incorporation of radioiron into myoglobin of the muscles of guinea‐pigs and rats was found to be depressed to a similar extent as into hemoglobin under the effect of exposure to a dose of (500–1,400 r of) roentgen rays, in contrast to hemins, the formation of which is not in close connection with mitotic processes as that of cytochrom b or ...

Science, 1992
Myoglobin was found in the nitrogen-fixing cyanobacterium Nostoc commune . This cyanobacterial myoglobin, referred to as cyanoglobin, was shown to be a soluble hemoprotein of 12.5 kilodaltons with an amino acid sequence that is related to that of myoglobins from two lower eukaryotes, the ciliated protozoa

Publisher Summary This chapter describes hemoglobin and myoglobin. Hemoglobin and myoglobin are, among all proteins, ones that have been, and are, most actively studied; an enormous number of papers have been published over the past hundred years on all aspects of their properties and behavior. The study of these proteins has gone beyond the interest

Structural Dynamics of Myoglobin
2008Protein structure is endowed with a complex dynamic nature, which rules function and controls activity. The experimental investigations that yield information on protein dynamics are carried out in solution; however, in most cases, the determination of protein structure is carried out by crystallography that relies on the diffraction properties of a ...

Myoglobin represents the stores of oxygen in muscle tissues. Because of its relatively small mol wt, myoglobin is often used in electrophoretic techniques as a mol wt marker, and also as a test for separation efficiency in capillary electrophoresis (CE).

Magnetic Resonance Studies of Met-Myoglobin and Myoglobin Azide
The Journal of Chemical Physics, 1967The variation of electron spin resonance lineshapes with orientation of single-crystal myoglobins are studied for high-spin (S=52) Fe3+ in met-myoglobin and low-spin (S=½) Fe3+ in myoglobin azide. It is found that for both these crystals random variations of about 2° in the orientation of the symmetry axes contribute significantly to the observed ...

Myoglobin, an intracellular haemoprotein expressed in the heart and oxidative skeletal myofibres of vertebrates, binds molecular oxygen and may facilitate oxygen transport from erythrocytes to mitochondria, thereby maintaining cellular respiration during periods of high physiological demand. Here we show, however, that mice without myoglobin, generated

Formation and Radiosensitivity of Myoglobin
Nature, 1955HAEMOGLOBIN is laid down in the maturing erythropoietic marrow cells. Exposure to ionizing radiation depresses the formation of new erythropoietic marrow cells and may destroy any such cells already present. Anaemia resulting from this interference manifests itself after the lapse of some days in a reduced erythrocyte count and reduced haemoglobin ...
