Full textAgars are red algal polysaccharides. These are composed of D-galactose with L-galactose alterned by glycosidic bond -1,4 and -1,3. These galactans harbor several modifications : sulfatations, methylations, pyruvylations. All these modifications hinder the agar degradation by marine bacteria. Zobellia galactanivorans is a marine flavobacterium able to degrade marine polysaccharides, including agars. The aims of this thesis are to identify and characterize the enzymatic tools of Z. galactanivorans to degrade the complex agar. The two subjects are a divergent -agarase (ZgAgaC) and sulfatases that act on agars. To perform this study on the agar specific enzymes, we have developed activity screens on a complex agar collection of substrates produced during the thesis. These screens have been used to show the divergent behaviour of ZgAgaC on complex agar compared to the other -agarases and -porphyranases of the family 16 (GH16). These screens were further used to identify the substrate of two sulfatases active on agar. To conclude, this work has allowed to develop different tools to identify new enzymatic activities and to have a better view of the agar catabolism of Z. galactanivorans

Full textHeterotrophic bacteria are key players in algal biomass recycling. Numerous works focused on the degradation of purified algal polysaccharides and discovered new enzymes and catabolic pathways. However, this strategy does not reflect the structural complexity of the algal extracellular matrix. In this thesis I implemented diverse approaches to decipher the ecological and metabolic strategies of bacteria specialized in the utilization of fresh macroalgae. I evidenced a succession of the epiphytic microbiota during in situ macroalgae decomposition. The presence of the known algal-polysaccharides degrader genus Zobellia was assessed on diverse macroalgae. Its abundance was season-dependent and particularly high on decaying algae. I demonstrated that Zobellia galactanivorans DsijT has the capacity to use fresh brown algae as a sole carbon source, highlighting a specific pioneer degrader behaviour. The analysis of its transcriptome revealed the induction of a subset of genes, including novel uncharacterized polysaccharide utilization loci (PULs), specifically induced with intact algae. The preliminary characterization of one of these PULs demonstrated its role in the degradation of fucose-containing sulfated polysaccharides and led to the discovery of novel enzymatic activities in Z. galactanivorans. Co-culture experiments showed that Z. galactanivorans supported the growth of Tenacibaculum spp. with macroalgae, bringing out cooperative interactions between pioneer and opportunist bacteria. By studying macroalgae degradation mechanisms at different scales, this thesis contributes to unveil the strategies of heterotrophic marine bacteria in the fate of macroalgal biomass

Full textLaminarin is a storage polysaccharide found in brown algae. Ectocarpus siliculosus has been recently established as a genetic and genomic model for brown algae. The analysis of its genome sequence revealed some candidate genes involved in the central metabolism of laminarin. In order to go onto functional studies, I have applied a medium throughput cloning strategy on these genes. Brown algae being an important coastal biomass, laminarin is also a significant carbon source for marine heterotrophic bacteria. The marine bacterium Zobellia galactanivorans is currently being established as a model bacterium for the bioconversion of algal polysaccharides. Its genome sequence encodes 5 putative laminarinases displaying various modular architectures. The heterologous expression and the purification of the catalytic modules ZgLamAGH16, ZgLamCGH16 and those of the carbohydrate-binding module CBM6 appended to ZgLamCCBM6, have enabled their biochemical characterization. Inactive mutants of the catalytic modules were obtained by site directed mutagenesis. They were used to generate enzyme-substrate complexes. The 3D-structure of ZgLamAGH16 was solved by X-ray crystallography, and oligoglucans of natural substrates were present in the catalytic site. ZgLamCGH16 was obtained in complex with a thio-hexasaccharide of β-1,3-glucan. The ZgLamCCBM6 structure associated with microcalorimetry experiments suggests that this CBM6 can bind laminarin simultaneously in its two binding clefts. The whole results are discussed and integrated in a biologic and evolutive context

Full textIn marine environment, biogenic emissions of iodinated compounds play an essential role in biogeochemical cycle of iodine. Nevertheless, enzymatic process involved in absorption and storage of iodine or in the synthesis of iodinated compounds are unknown marine organisms, especially in bacteria. Several genes, potentially involved in iodine metabolism, have been identified in the genome of a marine bacterium, Zobellia galactanivorans. One of these genes codes for a vanadium iodoperoxydase (VIPO), an enzyme specific of iodide oxidation. The main part of the thesis project was to understand molecular mechanisms controlling the specificity vanadium halopéroxydase (VHPO) for some halide, by studying the VIPO from Z. galactanivorans by directed mutagenesis and structural biology. To lead this project, twelve mutated enzymes were produced and characterized at biochemical level. For some of them, mutations lead to a loss of activity or to modification of catalytic properties or to a slight VBPO activity. The wild type enzyme and three mutants were also analyzed by X ray absorption and diffraction spectroscopy in order to link the structural modifications to their catalytic properties. The results of this study suggest that the main factor modulating the specificity in these enzymes is modification of redox potential of the peroxovanadate. Biochemical analyses lead with two other proteins identified in the genome of Z. galactanivorans. The first protein was characterized as a new VIPO. For the second protein, similar to mammal iodotyrosine deiodinase, the biochemical activity remains to be characterized. Z. galactanivorans seems to have several enzymes which oxidize iodide or split C-I bond. In parallel at this work, the localization and speciation of iodine were analyzed by chemical imaging in Z. galactanivorans and in the kelp L. digitata, known to concentrate highly iodide. All this information allow to a better understanding of molecular mechanisms involved in the specificity for halide in VHPO and the bacterial origin of these proteins. More generally, these studies assess to understand the role of iodine metabolism in some marine bacteria and there role in biogeochemical cycle of this element
