  • Title: [Denatured state of lysozyme in dimethyl sulfoxide].
    Author: Kirkitadze MD, Surin AK, Potekhin SA.
    Journal: Bioorg Khim; 1996 Jan; 22(1):20-3. PubMed ID: 8651952.
    Abstract:
    An influence of DMSO on lysozyme structure in solution was studied by fluorescence and optical rotary dispersion methods. Change in the protein structure was shown to proceed at DMSO concentration in water greater than 60% and result in an increase of the protein helicity. However, this structural state of lysozyme is similar to that of the unstructured peptides obtained by its complete proteolysis and is characterized by parameters of accessibility to solvent and mobility of their intrinsic chromophores. The data obtained evidenced that long range interactions have a little influence on the maintenance of the residual secondary structure of lysozyme in the presence of DMSO.
