Abstract

In the last few years, three laboratories have reported three entirely different crystallographic models for the L photointermediate of bacteriorhodopsin. All are from X-ray diffraction of illuminated crystals that contain L in photostationary states created at similar cryogenic temperatures. This article compares the models and their implications, the crystallographic statistics and the methods used to derive them, as well as their agreement with non-crystallographic information.

摘要

在过去几年里,三个实验室报告了细菌视紫红质L光中间体的三种完全不同的晶体学模型。所有模型都来自对在相似低温下形成的光稳态中含有L的光照晶体的X射线衍射。本文比较了这些模型及其含义、晶体学统计数据和用于推导它们的方法,以及它们与非晶体学信息的一致性。
