  • Abstract Ultraviolet difference spectra, solvent perturbation difference spectra, and temperature perturbation difference spectra indicate that tyrosyl residues of model compounds are affected by sodium dodecyl sulfate. This effect is dependent on the nature of the model compound, being enhanced by positive charges, and is attributed to partial masking of the tyrosyl chromophores by sodium dodecyl sulfate. With reduced carboxymethylated ribonuclease as a model, all three difference spectral… CONTINUE READING
