For industry-scale production of high-value chemicals in microbial cell factories, the elimination of metabolic flux imbalances is a critical aspect. However, a priori knowledge about the genetic design of optimal production pathways is typically not available. COMPASS, COMbinatorial Pathway ASSembly, is a rapid cloning method for the balanced expression of multiple genes in biochemical pathways. The method generates thousands of individual DNA constructs in modular, parallel, and high-throughput manner. COMPASS employs inducible artificial transcription factors derived from plant (Arabidopsis thaliana) regulators to control the expression of pathway genes in yeast (Saccharomyces cerevisiae). It utilizes homologous recombination for parts assembly and employs a positive selection scheme to identify correctly assembled pathway variants after both in vivo and in vitro recombination. Finally, COMPASS is equipped with a CRISPR/Cas9 genome modification system allowing for the one-step multilocus integration of genes. Although COMPASS was initially developed for pathway engineering, it can equally be employed for balancing gene expression in other synthetic biology projects.
