Effects of surfactant, salt and solvent on the structure and activity of adenosine deaminase: molecular dynamic and spectrophotometric studies.

Effects of sodium dodecyl sulfate, dodecyltrimethylammonium bromide, sodium chloride, sodium sulfate, methanol and ethanol, on the structure and activity of adenosine deaminase (ADA) were investigated by UV-Vis, circular dichroism spectrophotometry and molecular dynamics (MDs) studies. Relative activity, experimental and computational helix content, total accessible surface area (ASA) and exposed charged surface area (ECSA) were obtained. The relative activity of ADA in the absence and the presence of denaturants were compared with structural results.
