Title	Polybrominated diphenyl ethers interact with the key protein involved in carbohydrate metabolism in rice
Description	Rice exposed to organic pollutants such as polybrominated diphenyl ethers (PBDEs) usually experiences reduced biomass and increased soluble sugar content. This study showed that 2, 2', 4, 4'-tetrabromodiphenyl ether (BDE-47) led to increased glucose, fructose, and sucrose in rice leaves, accompanied by decreased photosynthetic rate and biomass. In order to identify the key enzyme that BDE-47 interacted with, a diazirine-alkynyl photoaffinity probe was designed, and photoaffinity labeling based chemoproteomics was conducted. Among all differentially expressed proteins, fructose-1, 6-bisphosphate aldolase (FBA) involved in carbohydrate metabolism was most likely the target protein of BDE-47. Spectral techniques and molecular docking analysis further revealed that the pollutant-protein interaction was driven by hydrophobic force. BDE-47 inhibited FBA catalytic efficiency by competing with its substrate, fructose-1, 6-diphosphate (F-1, 6-P), leading to soluble sugar accumulation, photosynthetic rate decline and biomass reduction. This study unraveled the influencing mechanism of PBDEs on rice by combining the novel photoaffinity labeling-based chemoproteomics with conventional proteomics. The improved knowledge on direct interaction between organic pollutants and proteins will help alleviate the harmful effects of soil pollution on plants.
