The marine bacteria Vibrio diabolicus produces an exopolysaccharide (EPS) called HE800. The native form of HE800 has already shown biological efficiency in bone healing. It is studied as glycosaminoglycan-mimetic for applications in cosmetic and human health. To enhance biotechnological applications of polysaccharides, the chemical structures should be properly controlled; moreover, the production yield could also be a bottleneck. The genetic cluster of the HE800 EPS biosynthesis has been identified in 2014. However, the biosynthesis molecular mechanisms and regulations remain sometimes unclear. The main objective of this work is to obtain a recombinant production of the HE800 EPS in the common host Escherichia coli, to improve the knowledge of its... |

Although polysaccharides are ubiquitous and the most abundant renewable bio-components, their studies, covered by the glycochemistry and glycobiology fields, remain a challenge due to their high molecular diversity and complexity. Polysaccharides are industrially used in food products; human therapeutics fall into a more recent research field and pharmaceutical industry is looking for more and more molecules with enhanced activities. Glycosaminoglycans (GAGs) found in animal tissues play a critical role in cellular physiological and pathological processes as they bind many cellular components. Therefore, they present a great potential for the design and preparation of therapeutic drugs. On the other hand, microorganisms producing exopolysaccharides (EPS)... |
