Efficient DNA assembly methods are essential tools for synthetic biology and metabolic engineering. Among several recently developed methods that allow assembly of multiple DNA fragments in a single step, DNA assembly using type IIS enzymes provides many advantages for complex pathway engineering. In particular, it provides the ability for the user to quickly assemble multigene constructs using a series of simple one-pot assembly steps starting from libraries of cloned and sequenced parts. We describe here a protocol for assembly of multigene constructs using the modular cloning system (MoClo). Making constructs using the MoClo system requires to first define the structure of the final construct to identify all basic parts and vectors required for the construction strategy. Basic parts that are not yet available need to be made. Multigene constructs are then assembled using a series of one-pot assembly steps with the set of identified parts and vectors.
