A small-angle X-ray scattering study of the structure of lysozyme-sodium dodecyl sulfate complexes.
The structure of lysozyme-sodium dodecyl sulfate (SDS) complexes in solution is studied using small-angle X-ray scattering (SAXS). The SAXS data cannot be explained by the necklace and bead model for unfolded polypeptide chain interspersed with surfactant micelles. For the protein and surfactant concentrations used in the study, there is only marginal growth of SDS micelles as they complex with...
متن کاملUnfolding and folding pathway of lysozyme induced by sodium dodecyl sulfate.
Proteins may exhibit an unfolding or folding state in the presence of a surfactant. In the present study, the unfolding and folding pathway of hen egg white lysozyme (HEWL) induced by sodium dodecyl sulfate (SDS) is studied. The stoichiometry obtained from isothermal titration calorimetry (ITC) provides guidelines for other techniques. The fluorescence spectra and circular dichroism show that t...
متن کاملSynergistic sphere-to-rod micelle transition in mixed solutions of sodium dodecyl sulfate and cocoamidopropyl betaine.
Static and dynamic light scattering experiments show that the mixed micelles of sodium dodecyl sulfate (SDS) and cocoamidopropyl betaine (CAPB) undergo a sphere-to-rod transition at unexpectedly low total surfactant concentrations, about 10 mM. The lowest transition concentration is observed at molar fraction 0.8 of CAPB in the surfactant mixture. The transition brings about a sharp increase in...
متن کاملBacterial Utilization of Sodium Dodecyl Sulfate
SDS is widely used detergent in house holds and Industry. It is known to be toxic to fishes and also to animals. In the present review, we have emphasized on biodegradation of this detergent by bacteria, the pathway of biodegradation and also the enzymes involved in the degradation.
متن کاملTHE EFFECT OF IONIC STRENGTH ON THE BINDING OF SODIUM N-DODECYL SULPHATE TO ASPERGILLUS NIGER CATALASE
The binding of sodium n-dodecyl sulphate (SDS) to Aspergillus niger catalase in various ionic strengths at pH 6.4 and a temperature of 27? and 37?C has been studied over a range of SDS concentrations using equilibrium dialysis and fluorescence spectroscopy techniques. The binding data were used and interpreted in terms of theoretical models (Scatchard Equation and Wyman Binding Potential). ...
