摘要:

紫色酸性磷酸酶(PAPs)是一类广泛存在于植物体内的金属磷酸酯酶, 其羧基端含有1个保守结构域, 由5个保守基序和7个氨基酸残基构成。作为一种特殊的酸性磷酸酶, PAPs在酸性环境下能够有效催化磷酸酯或酸酐的水解, 释放出植物可以利用的磷酸基团。此外, PAPs在调节植物碳代谢、细胞壁合成和抵御病菌侵染等方面也发挥重要生理作用。该文简要介绍了PAPs的结构、家族成员及其调控因子, 并着重总结了近年来对PAPs生物学功能的研究进展, 为今后系统开展PAPs功能研究提供了理论参考。

Abstract:

Purple acid phosphatases (PAPs) are members of the metallo-phosphoesterase family identified from a wide range of plants. They are characterized by the presence of five conserved structure motifs and seven amino acid residues in the C-terminal. PAPs have mostly been studied for their potential involvement in phosphorus acquisition and redistribution because of their ability to catalyze the hydrolysis of activated phosphate esters and anhydrides under acidic conditions. Recent studies also showed that PAPs play important roles in modulating plant carbon metabolism, cell wall synthesis and pathogen resistance, etc. This review focuses on the structure, family members and regulatory factors of PAPs, with special emphasis on the recent progress of their biological functions, which will provide theoretical reference for further study of PAPs in plants.

Key words: purple acid phosphatases (PAPs), biological function, regulatory factors
