Abstract

Abiotic stress tends to induce oxidative damage to enzymes and organelles that in turns hampers the phosphorylation process and decreases the adenosine triphosphate (ATP) productivity. Artificial assemblies can alleviate abiotic stress and simultaneously provide nutrients to diminish the oxidative damage. Here, we have integrated natural acid phosphatase (ACP) and ATP synthase with plasmonic Au clusters in a biomimetic microreactor. ACP immobilized on the Au clusters is harnessed to generate proton influx to drive ATP synthase and concurrently supply phosphate to improve phosphorus availability to combat phosphorus-deficiency stress. In tandem with the reactive oxygen species (ROS) scavenging and the photothermal functionality of Au clusters, such an assembled microreactor exhibits an improved abiotic stress tolerance and achieves plasmon-accelerated ATP synthesis. This innovative approach offers an effective route to enhance the stress resistance of ATP synthase-based energy-generating systems, opening an exciting potential of these systems for biomimicking applications.
