Research Topic Description, including Problem Statement:
Genetic material and proteins can be synthesized using synthetic biological monomers which are not found in the natural world. These can elicit significant structural and functional changes, with the potential for phenotypic consequences in organisms. Semi-synthetic organisms have already been generated incorporating synthetic nucleotides – E.coli using synthetic base pairs have been generated and have been shown to replicate, engineered using synthetic biology techniques. Synthetic or unnatural amino acids with novel characteristics have also been incorporated in protein engineering, with incorporation of unnatural amino acids demonstrated in both prokaryotic and eukaryotic cells, generating proteins with novel biochemical properties.
The ability to generate new forms of life using synthetic monomers could enable organisms to take on modified or new characteristics, including novel harmful effects or increased pathogenicity. Similarly, the incorporation of unnational amino acids into protein structures may allow the development of modified or novel toxins with enhanced or varied effects, such as increased toxicity. These applications for non-natural biological components could therefore present a biosecurity risk that is currently poorly understood.
Changes to fundamental biological building blocks and their incorporation into genetic or protein sequences may also have consequences for detection, whereby the success of current detection technologies are contingent on the recognition of naturally occurring microorganisms or sequences. Unnatural or synthetic components may bypass detection technologies, enabling their existence and impacts challenging to identify and attribute.
In order to address and mitigate these biosecurity risks, this proposal seeks to characterize the potential range of physiological impacts of biological materials and microorganisms comprised of synthetic monomers and better understand the impacts on the utility of current detection technologies, to support future detection and attribution capabilities
A possible approach may include:
Reviewing and exploring existing and novel research on unnatural and synthetic biological monomers to characterize how their incorporation into biological components and systems to generate semi-synthetic products (from molecules to microorganisms) can lead to changes in properties and structure/function relationships. This might include:
Relevance to the Intelligence Community:
The incorporation of synthetic biological monomers e.g. nucleotides and amino acids into biological products and microorganisms may present a biosecurity risk, as the incorporation can impart structural and functional changes which in turn could lead to a different physiological effects. In addition, detection technologies developed for naturally occurring biological organisms and molecules may not recognize semi-synthetic versions, allowing their use to go undetected. In order to mitigate this risk, additional information is needed to characterize the changes that occur to the function of biological materials when synthetic components are incorporated, the types of physiological effects these can cause and the detection requirements to identify their use.
