Studies on Myoglobin I. the Solwility of Myoglobin in Concentrated Ammonium Sulfate Solutions
The crystallization by Theorell (8) of one of the hemoglobins of muscle, horse heart myoglobin, has made possible the more accurate study of this interesting protein, and opened the way for the investigation of other members of the series. Previously the question of the existence of a protein in the muscle resembling, but nevertheless distinct from, blood hemoglobin was in doubt. Theorell’s wor...
متن کاملStudies on human myoglobin. II. Fetal myoglobin: its identification and its replacement by adult myoglobin during infancy.
By KARL SINGER, BASIL ANGELOPOULOS AND BRACHA RAMOT I T IS N(.)W well established that the erythrocytes of normal newborns contain about 50 to 90 per cent of fetal (type F) hemoglobin, the remainder being supplied by the normal adult (type A) pigment. As a rule, the fetal hemoglobin is rapidly replaced by the adult compound and after 7 to 12 months the embryonic pigment is no longer demonstrabl...
متن کاملResonance Raman Studies of Heme Axial Ligation in H93G Myoglobin
The resonant Raman active mode identified in numerous studies as the heme iron-histidine stretch has been systematically investigated in the Raman spectrum of 15 exogenous ligands to the heme iron in the myoglobin proximal cavity mutant H93G. Mutation of the native histidine 93 of myoglobin to glycine (H93G) creates a cavity at the heme iron that can be filled with exogenous ligands. Substitute...
متن کاملProton nuclear magnetic resonance studies of myoglobin in H2O.
Exchangeable hydrogens in proteins can be identified by comparison of nuclear magnetic resonance spectra obtained in H(2)O and in D(2)O. In oxymyoglobin and myoglobin we have been able to observe resonances of the NH protons of the two tryptophans, as well as one resonance from arginine and one from histidine in the range -10 to -15 ppm downfield from 3-(trimethylsilyl)propanesulfonic acid (sod...
متن کاملStudies on the oxygen and carbon monoxide equilibria of human myoglobin.
The reactions of hemoglobin (Hb) and myoglobin (Mb) with gas are, for the particular mechanisms involved, one of the most interesting problems in biochemistry. In spite of a great number of researches on the gaseous equilibria of Hb from different animal species, Mb has not been extensively investigated from this point of view. The classical work by Theorell (1) with crystallized horse Mb appea...
