转运蛋白的主要易化剂超家族(MFS)由三类膜转运蛋白组成:同向转运蛋白、单向转运蛋白和反向转运蛋白。尽管功能如此多样,但MFS转运蛋白被认为在其不同的转运周期内经历类似的构象变化,称为摇杆开关机制。虽然构象变化之间的相似性是值得注意的,但差异也很重要,因为它们可能解释MFS超家族的同向转运蛋白、单向转运蛋白和反向转运蛋白的不同功能。我们回顾了各种实验和计算的结构数据上的选择数量的反向,同向和单向转运蛋白从MFS家庭比较的相似性和差异的构象动力学的三个不同类别的转运蛋白。
The major facilitator superfamily (MFS) of transporters consists of three classes of membrane transporters: symporters, uniporters, and antiporters. Despite such diverse functions, MFS transporters are believed to undergo similar conformational changes within their distinct transport cycles, known as the rocker-switch mechanism. While the similarities between conformational changes are noteworthy, the differences are also important since they could potentially explain the distinct functions of symporters, uniporters, and antiporters of the MFS superfamily. We reviewed a variety of experimental and computational structural data on a select number of antiporters, symporters, and uniporters from the MFS family to compare the similarities and differences of the conformational dynamics of three different classes of transporters.
