Method Circular dichroic measurements with purified lac permease
Comments "Circular dichroic measurements with purified lac permease have indicated that 85±5% of the amino acid residues are arranged in helical secondary structures whether the protein is solubilized in octylglucoside or reconstituted into proteoliposomes (primary source)."
