摘　　要：P_(1B)-ATPases是在生物中广泛存在的一类可通过水解ATP跨膜运送重金属离子的蛋白,是P型ATPase家族的一个亚类。研究发现P1B-ATPases在植物中主要负责重金属离子的主动转运,在植物重金属平衡调节系统中发挥重要作用。文中从P_(1B)-ATPases的结构与分类出发,介绍了P_(1B)-ATPases的作用机制,综述了目前P_(1B)-ATPases功能的研究进展,以期为未来P_(1B)-ATPases在改良作物品质以及生态环境治理的研究及应用提供参考。P_(1B)-ATPases are a group of proteins that can transport heavy metal ions across membranes by hydrolyzing ATP and they are a subclass of the P-type ATPase family. It was found that P_(1B)-ATPases are mainly responsible for the active transport of heavy metal ions in plants and play an important role in the regulation of heavy metal homeostasis in plants. In this paper, we dissusses the mechanism of P_(1B)-ATPases from the structure and classification of P_(1B)-ATPases, and review the current research progress in the function of P_(1B)-ATPases, in order to provide reference for future research and application of P_(1B)-ATPases in improving crop quality and ecological environment management.
