Streptomycetaceae is one of the most diverse and commercially valuable taxa-producing antibiotics, and the Streptomycetaceae genome contains an extremely rich resource of natural product biosynthesis gene clusters, which makes Streptomyces chassis cells uniquely suited as heterologous expression hosts. Based on the principles of synthetic biology, CD BioGlyco conducts research and Development of Chassis Cells to prepare heterologous high-yielding chassis strains and use them for the Production of more active compounds.
Here, we provide professional Streptomycetaceae engineering service with our high level of multidisciplinary skills.

We utilize the minimal genome to serve as a chassis microbe for heterologous expression. Second, we eliminate competition for substrate, energy and reducing power in the Streptomycetaceae metabolic pathway by knocking out the original secondary metabolite biosynthesis gene cluster, which reduces the difficulty of detection and purification of the heterologous product and enhances the yield of the heterologously expressed target.
Among other things, we offer a variety of knockout tools to our clients:
Clustered regularly interspaced short palindromic repeats (CRISPR) system
Transcription activator-like effector nucleases (TALENs)
Others
We use gene editing technologies to modify (knockout, replacement, etc.) regulatory factors to silence or overexpress pre-existing biosynthetic gene clusters in Streptomycetaceae. This approach eliminates metabolite interference effects or improves heterologous expression yields and optimizes chassis cell performance.
For example, we replace the original promoters in the Streptomycetaceae gene cluster with promoters induced by other microorganisms, resulting in improved yields and optimized heterologous expression systems for Streptomycetaceae.
We alter the metabolic pathways of Streptomycetaceae by combinatorial biosynthesis to increase substrate and precursor content. For example, we optimize the heterologous expression of target products by expressing genes related to enzymes in the Streptomycetaceae chassis. Knocking down specific genes of the enzyme to increase the enzyme level enhances the precursor supply for heterologous expression of the target product.
