生物膜定义了细胞的边界,并划分了生命所需的化学和物理过程。许多生物过程是由嵌入或与这种膜相关的蛋白质进行的。在原子或近原子分辨率下测定膜蛋白(MP)结构在阐明其在生物学中的结构和功能影响方面起着至关重要的作用。截至2021年初,这项奋进已确定了1198个独特的MP结构。1985年,第一个原子MP结构被阐明后,这些结构的价值通过将它们的三维(3D)坐标存入蛋白质数据库(PDB)而大大扩展。从那时起,免费获得MP结构有助于更广泛和更深入地了解MP,这为了解其生物学功能提供了重要的新见解。在这里,我们强调了新技术演变中代表性MP和里程碑的结构和功能生物学,并深入了解PDB在放大其影响方面的关键发展。
Biological membranes define the boundaries of cells and compartmentalize the chemical and physical processes required for life. Many biological processes are carried out by proteins embedded in or associated with such membranes. Determination of membrane protein (MP) structures at atomic or near-atomic resolution plays a vital role in elucidating their structural and functional impact in biology. This endeavor has determined 1198 unique MP structures as of early 2021. The value of these structures is expanded greatly by deposition of their three-dimensional (3D) coordinates into the Protein Data Bank (PDB) after the first atomic MP structure was elucidated in 1985. Since then, free access to MP structures facilitates broader and deeper understanding of MPs, which provides crucial new insights into their biological functions. Here we highlight the structural and functional biology of representative MPs and landmarks in the evolution of new technologies, with insights into key developments influenced by the PDB in magnifying their impact.
