Abstract

The three-dimensional (3D) structure of the crystalline surface layer of Aeromonas hydrophila has been determined to a resolution of 1.3 nm by crystallographic electron microscopy. The S-layer has tetragonal symmetry, with a unit cell dimension of 12.0 nm and a thickness of 5.6 nm. The 3D reconstruction reveals a distinct domain structure, with one main protein mass at one of the fourfold symmetry axes and a minor part at the other.

摘要

嗜水气单胞菌晶体表面层的三维（3D）结构已通过晶体学电子显微镜确定，分辨率为1.3纳米。S层具有四方对称性，晶胞尺寸为12.0纳米，厚度为5.6纳米。三维重建揭示了一种独特的结构域结构，在四重对称轴之一处有一个主要蛋白质块，在另一个四重对称轴处有一个较小的部分。
