halobium halobium紫色膜的红外光谱具有酰胺I和酰胺A频率,对于标准的α -螺旋结构来说异常高。正常模式计算表明,这些和其他不寻常的光谱特征可以归因于α 11-螺旋。这样的结构表明,螺旋骨架可能提供了质子传输发生的框架。
The infrared spectrum of the purple membrane of Halobacterium halobium has amide I and amide A frequencies that are anomalously high for standard alpha-helical structures. Normal mode calculations indicate that these and other unusual features of the spectrum can be attributed to alpha 11-helices. Such structures suggest that the helix backbone may provide the framework through which proton transport takes place.
