植物细胞质膜H+-ATPase的结构与功能

植物细胞质膜H+-ATPase属于P型质子泵。由该酶产生的跨膜电化学梯度是物质跨膜运输的原初动力。研究表明，质膜H+-ATPase与植物的生长发育密切相关，被称为植物细胞的“主宰酶”。近年，关于该酶的生化特性，基因表达与调控以及结构与功能等方面的研究取得重要进展。对质膜H+-ATPase的生化特性，分子结构，调节机制和生理功能等进行了综述。

Structure and Function of Plant Plasma Membrane H+-ATPase

Plant plasma membrane H+ -ATPase was a P-type proton pump. The transmembraneelectrochemical gradients generated by the enzyme was the primary force for the transmembranetransports. Researches indicated that the plasma membrane H+ -ATPase plays important roles in the growth and development in plants. It was called the "master enzyme" in plant cells; Great progress had been made about the biochemical character, gene expression and regulation, structure and function of the H+ -ATPase in recent years. In this article the biochemical character, molecular structure, regulatory mechanism and physiological roles of the plasma membrane H+ -ATPase were reviewed.
