Optical Rotatory Dispersion and Conformation of Various Globular Proteins.
The crucial test regarding the usefulness of the optical rotatory dtspersion method for the study of protein conformation was in confronting the results of this method w&the x-ray structural analysis of myoglobm. The high resolution x-ray structural analysis of Kendrew et al. on myoglobin crystals (1) and the optical rotation studies of Beychok and Blout (2) and Urnes, Imahori, and Doty (3) on ...
متن کاملOptical Rotatory Dispersion and Conformation of Polyadenylic and Polyuridylic Acids.
The application of optical rot,atory dispersion to nucleic acids and polynucleotides is fairly recent (l-6). Doty et cd. (2) made a comprehensive study of the optical rotatory dispersion of deoxyribonucleic acid, ribonucleic acid, and complexes of some homopolynucleotides; their results strongly suggested a close relationship between the optical rotations and the secondary structure of nucleic ...
متن کاملOptical Rotatory Dispersion and the Twist Conformation of Cyclohexanones.
The Octant Rule1 provides a theoretical basis for the study of optical rotatory dispersion curves of ketones. The application of this rule to extensive collections of data for cyclohexanone types from our two laboratories has been described elsewhere.2 3 Among the hundreds of curves recorded, a few stand out by reason of their unusually large amplitudes (positive or negative), which cannot be r...
متن کاملOptical rotatory dispersion of nonhelical proteins.
The optical rotatory dispersion of a group of proteins having the Moffitt constant bo near zero was studied in the far ultraviolet spectral zone. Sodium poly-c+L-glutamate, myoglobin, and serum albumin were used as reference substances. It was found that, in addition to the normal type of rotatory dispersion, as displayed, for example, by myoglobin, four other types of curves could be demonstra...
متن کاملThe ultraviolet rotatory dispersion and conformation of Bence-Jones proteins.
The optical rotatory dispersion of five individual specimens of Bence-Jones proteins was investigated, including the far ultraviolet spectral zone. The Mo5tt constants (bo) were determined, and either low positive or low negative values were found. The rotatory dispersion curves of all specimens had flat negative minima at 220 to 235 rnp and positive maxima at 204 to 212 rnp. Denaturation with ...
