A classical Raman vibrational spectroscopic study of conformational changes in Saccharomyces cerevisiae invertase after denaturation by temperature or pressure is described. Spectra were obtained from enzyme solutions and from lyophilized forms for native invertase and after pressure-or temperature-
## Abstract The highβresolution nmr spectrum of baker's yeast tRNA, a recently sequenced nonβdenaturable tRNA, has been compared with the spectra of the native and denatured conformers of the closely related species tRNA. Because of the presence of many common base pairs in the different tRNA's, it
Ultraviolet resonance Raman spectroscopy was used to probe the change in the average environment of the seven tyrosine amino acids in barnase when the polypeptide chain folds from the denatured to the native state. The excitation radiation was continuous wave at a wavelength of 244 nm, and was gener
