Protocol for connector-enabled multigene pathway assembly using Golden Gate Assembly and yeast recombination

Here, we present a protocol for multigene pathway construction in Saccharomyces cerevisiae using a connector-enabled workflow that integrates Golden Gate Assembly with yeast homologous recombination. We provide procedures for assembling Level 1 transcriptional unit (TU) fragments using standardized connectors and directly co-transforming them into S. cerevisiae to form Level 2 multigene plasmids. Compared to conventional approaches, this protocol significantly reduces procedural complexity, minimizes dependence on operator expertise, and substantially accelerates workflow timelines. For complete details on the use and execution of this protocol, please refer to Seong et al. 1
