The structural dynamics of myoglobin [PDF]
Journal of Structural Biology, 2004 Conformational fluctuations in proteins were initially invoked to explain the observation that diffusion of small ligands through the matrix is a global phenomenon. Small globular proteins contain internal cavities that play a role not only in matrix dynamics but also in controlling function, tracing a pathway for the diffusion of the ligand to and ...

Wahrend der Schwangerschaft kommt es zu einer Zunahme des Myoglobingehaltes des Myometriums von 22,7 mg-% auf 64,8 mg-% Frischgewicht. Der Anstieg ist im letzten Trimenon am deutlichsten ausgepragt; im 7.–8. Schwangerschaftsmonat bestimmen wir noch einen Myoglobingehalt von 34,8 mg-% im Myometrium des Corpus uteri.

Myoglobin reconstituted with iron porphycene catalyzes the cyclopropanation of styrene with ethyl diazoacetate. Compared to native myoglobin, the reconstituted protein significantly accelerates the catalytic reaction and the kcat/Km value is 26-fold ...

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

Nitrite coordination in myoglobin
Journal of Inorganic Biochemistry, 2017The coordination of nitrite in myoglobin (Mb) has been characterized by resonance Raman spectroscopy and the frequencies of the nitrite bound to the heme Fe as well to the 2-vinyl have been computed by density functional theory (DFT) calculations. The DFT Natural Bond Orbital (NBO) analysis and the extensive isotope-labeling in the resonance Raman ...

Publisher Summary This chapter presents procedures for the isolation of intracellular oxygen-binding proteins of tissues, called “tissue hemoglobins” in the widest sense. All of these, except Ascaris and yeast hemoglobin, are monomers or dimers having a minimum molecular weight of 18,000 with similar optical spectra and chemical reactivity ...

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 ...

Manganese(V) Porphycene Complex Responsible for Inert C-H Bond Hydroxylation in a Myoglobin Matrix.
Journal of the American Chemical Society, 2017A mechanistic study of H2O2-dependent C-H bond hydroxylation by myoglobin reconstituted with a manganese porphycene was carried out. The X-ray crystal structure of the reconstituted protein obtained at 1.5 Å resolution reveals tight incorporation of the ...

Abstract The myoglobin content of the skeletal muscles of the rat was found to vary between 0.7 and 1.2 mg./g. fresh muscle. The content of cytochrome c which is extractable with water was found to vary between 0.0122 and 0.0187 mg./g. fresh muscle.
