Computatioanl Study on Interactions of Heavy-Elements with Biologically Important Ligands
EMSL Project ID
47713
Abstract
Actinides have lead to increased environmental contamination and public health concern due to their introduction into groundwater and natural environments via various human activities. In order to understand the chemical and radiological toxic effects of actinides elements, it is crucial to understand the mechanisms of actinide uptake and transport by specific biomolecules. A key step is to identify the protein binding sites with selective recognition to actinides and the biochemical mechanisms of binding and unbinding processes at molecular level. We will focus on the fundamental understanding of the interactions between uranyl cation and small bio-ligands in aqueous solution using QM/MM and AIMD methods. The ultimate goal of this project is to build the fundamental understanding of physico-chemical interactions that drive the affinity of chelating ligands for uranyl and the key pathways involved, thus a step towards rational design of potential efficacious therapies for removing toxicity of actinyl and remediation technologies for environmental contaminants.
