The discovery, by scientists in the York Structural Biology Laboratory and the Centre for Novel Agricultural Products, will support the development of plants that can help tackle pollution caused by royal demolition explosive, also known as RDX.
Researchers at York have identified bacteria that use RDX as a food source and used that knowledge to develop transgenic plants that can draw pollutants out of the soil and break them down.
The latest findings, published in The Journal of Biological Chemistry, focus on the XplA enzyme which plays an important role in that process.
Dr Gideon Grogan, from the York Structural Biology Laboratory, said: “The biological process for tackling the pollution caused by RDX already exists but we need to find ways of making it work faster and on the scale required.
“This research significantly improves our understanding of the structure of this enzyme and is therefore an important step towards exploiting its unusual properties.”
Professor Neil Bruce, from the Centre for Novel Agricultural Products, said: “RDX is toxic and a possible carcinogen so it is important to identify ways of stopping it polluting land and water supplies.
“We have already had significant success in engineering plants that can perform this task and this research will help further refine that technique.”
The research is funded by the Centre of Excellence for Biocatalysis, Biotransformations and Biocatalytic Manufacture (CoEBio3), Biotechnology and Biological Sciences Research Council and the Strategic Environmental Research and Development Program (SERDP) of the US Department of Defense.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
