Abstract

The effect of pressure on the unfolding of the molten globule (MG) state of canine milk lysozyme (CML) was examined using ultraviolet spectroscopy. The volume changes of the MG-unfolded-state transition were observed at pH 2.0 and around 20 to 60°C, but no volume change has been found for bovine α-lactalbumin, which is homologous to CML. Our results suggest that the MG state of CML possesses a tightly packed hydrophobic core.
