Thermostability of Rhodopseudomonas viridis and Rhodospirillum rubrum chromatophores reflecting physiological conditions

►The dynamics of intact membranes is fundamental for understanding the functions. ►Effect of growth conditions on between dynamics was examined for two chromatophores. ►DSC of the two membranes exhibited different temperature dependence. ►The difference was evaluated well in terms of protein-lipid rate and specificity.
