Thee fluorescence and circular dichroism (CD) spectra of H protein increased upon binding to intact LPS and a partially deacylated derivative. In contrast, completely deacylated derivatives showed lower affinities and almost no fluorescence or CD changes of H protein. These results demonstrate that the lipid part of LPS is responsible for the conformational change of minor spike H protein, which would function as a trigger for phage DNA ejection for infection of the host cell., φX174ファージ感染を司るスパイクHタンパク質の機能と構造}, title = {Crucial role of the lipid part of lipopolysaccharide for conformational change of minor spike H protein of bacteriophage φX174}, year = {2005} }
