Abstract

An anion channel of the chloroplast envelope was previously shown to be involved in protein import. Some gating characteristics of the channel are presented. The pore size of the channel is estimated to be around 6.5 A. Antibodies raised to Tic110 completely inactivate the protein import-related channel. These observations suggest that the channel is associated with the Tic machinery and can function as the protein conducting channel of the inner envelope membrane.

摘要

叶绿体被膜的一种阴离子通道先前已被证明与蛋白质导入有关。本文介绍了该通道的一些门控特性。该通道的孔径估计约为6.5埃。针对Tic110产生的抗体可使与蛋白质导入相关的通道完全失活。这些观察结果表明，该通道与Tic机制相关，可作为内膜的蛋白质传导通道发挥作用。
