E. coli engineered to synthesise chondroitin sulfate [Full subscriber]

Sulfated glycosaminoglycans (GAGs) are a class of important biologics that are currently manufactured by extraction from animal tissues. Although such methods are unsustainable and prone to contamination, animal-free production methods have not emerged as competitive alternatives due to complexities in scale-up, the requirement for multiple stages and the cost of co-factors and purification. Now, researchers at the Rensselaer Polytechnic Institute, US have developed one-step biosynthesis of chondroitin sulfate (CS), a type of GAG, a polysaccharide molecule used in pharmaceuticals and nutraceuticals, via reprogrammed E. coli.…
