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
