Abstract
A method of determining the phases of X-ray reflections from oriented model membrane systems at low resolution is described. The method involves deconvolution and requires that d less than or equal to 2v where v is the width of the head group region within the bilayer and d is the thickness of the bilayer. The method can be used with a single set of X-ray data and applies to lipid bilayers which have a relatively constant density in the hydrocarbon region. Phases for the first five or six orders of phosphatidylethanolamine and lecithin are derived. A refined analysis based upon deconvolution but using information inherent in the Fourier profile is also described.
摘要
描述了一种在低分辨率下确定来自取向模型膜系统的X射线反射相位的方法。该方法涉及去卷积，并且要求d≤2v，其中v是双层内头部基团区域的宽度，d是双层的厚度。该方法可用于单组X射线数据，并适用于在烃区域具有相对恒定密度的脂质双层。推导了磷脂酰乙醇胺和卵磷脂前五个或六个级次的相位。还描述了一种基于去卷积但使用傅里叶轮廓中固有信息的精细分析。
