摘要: 叶绿体内膜上存在有磷酸丙糖转运器。本文着重对该转运器的结构和功能、转运特性及其对光合作用的调节等做一介绍。磷酸丙糖转运器能够催化磷、磷酸丙糖和3磷酸甘油酸的反向交换运输,从而使光合初级产物从叶绿体转运到胞质。在生理条件下,这种转运严格遵循1∶1的反向交换原则,并且转运活性受光的调节。目前,已经从一些植物中分离到磷酸丙糖转运器蛋白,并克隆了它们的cDNA。近年来,利用基因工程手段对磷酸丙糖转运器功能的研究也取得了很重要的进展。

Abstract: The export of primary photosynthesis products from chloroplasts into t he cytoplasm is mediated by the triose phosphate translocators(TPT).The transporter is an integral membrane protein localized at the inner envelop of chloroplasts.This review focuses on aspects of the functions,the structures and the transport characteristics of TPT and gives an account of the progress achieved in this fields in the last decade.
