摘要

用差示扫描量热法研究了角质盐杆菌的热转变。在加热曲线上观察到两个明显的峰,对应于两种主要蛋白质成分的变性。其中一个峰被指定为包膜糖蛋白的变性。随着葡萄糖、甘油、NaNO3和NaSCN的加入,变性温度的变化与之前提出的疏水相互作用对稳定糖蛋白至关重要的观点一致。

A calorimetric study of the thermal transitions of Halobacterium cutirubrum.

The thermal transitions of Halobacterium cutirubrum have been examined by differential scanning calorimetry. Two distinct peaks corresponding to the denaturation of two major protein components were observed in the heating curves. One of the peaks has been assigned to the denaturation of the envelope glycoprotein. The variations of the denaturation temperatures with the addition of glucose, glycerol, NaNO3, and NaSCN are consistent with the previous proposal that hydrophobic interactions are essential in stabilizing the glycoprotein.
