| 摘 要： | 酸性磷酸酶（APase）是酸性条件下（pH < 7.0）能催化磷酸单酯或酸酐裂解从而释放无机磷酸根离子的水解酶类。紫色酸性磷酸酶（Purple acid phosphatase,PAP）是一类特殊的酸性磷酸酶,其具有鲜明的特征,如：酶的提取液呈紫色或粉色、酶活性不受酒石酸盐抑制、氨基酸序列具有5个保守结构域和双金属离子催化中心等。已有的研究表明,紫色酸性磷酸酶在植物适应低磷胁迫过程中发挥着重要作用。本文综述了紫色酸性磷酸酶的生化特性、亚细胞定位、生物学功能以及最新研究进展。

| Abstract: | Acid phosphatase (APase) belongs to the hydrolase enzyme, which hydrolyzes orthophosphate from phosphomonoester or anhydride with an acidic pH optimum (pH < 7.0). Among APase, purple acid phosphatase (PAP) has distinctive biochemical and molecular characteristics, such as appearing purple or pink in extracted enzyme solutions, insensitive activity to tartrate inhibition, harboring of a binuclear metal center and five conserved motif blocks in amino acid sequences. It has been documented that PAP plays an important part in plant adaptation to phosphorus deficiency. In this review, we summarized the biochemical characterization, subcellular localization, biological function, and recent research progress of PAP in plants. |
