DNA assembler method for construction of zeaxanthin-producing strains of Saccharomyces cerevisiae.

DNA assembler enables design and rapid construction of biochemical pathways in a one-step fashion by exploitation of the in vivo homologous recombination mechanism in Saccharomyces cerevisiae. It has many applications in pathway engineering, metabolic engineering, combinatorial biology, and synthetic biology. Here we use the zeaxanthin biosynthetic pathway as an example to describe the key steps in the construction of pathways containing multiple genes using the DNA assembler approach. Methods for the construction of the clones, S. cerevisiae transformation, and zeaxanthin production and detection are shown.
