There is a need in synthetic biology for flexible fully designed vectors to address challenging cloning strategies. This article presents a new method for plasmid synthesis that paves the way for exploring protein interactions.
A need in synthetic biology is the ability to precisely and efficiently make flexible fully designed vectors that addresses challenging cloning strategies of single plasmids that rely on combinatorial co-expression of a multitude of target and bait fusion reporters useful in projects like library screens. For these strategies, the regulatory elements and functional components need to correspond perfectly to project specific sequence elements that facilitate easy exchange of these elements. This requires systematic implementation and building on recent improvements in Golden Gate (GG) that ensures high cloning efficiency for such complex vectors. Currently, this is not addressed in the variety of molecular GG cloning techniques in synthetic biology. Here, we present the bottom-up design and plasmid synthesis to prepare 10 kb functional yeast secrete and display plasmids that uses an optimized version of GG in combination with fluorogen-activating protein reporter technology. This allowed us to demonstrate nanobody/target protein interactions in a single cell, as detected by cell surface retention of secreted target proteins by cognate nanobodies. This validates the GG constructional approach and suggests a new approach for discovering protein interactions. Our GG assembly platform paves the way for vector based library screening and can be used for other recombinant GG platforms.
