For three days our group retreated to the island of Neuwerk, in the middle of the Wadden Sea National Park in the German Bight, one of our main research areas. We had fruitful discussions and were able to explore the Wadden Sea on foot.
We welcome Nadine Gerlach as new PhD student in our group.
Participation in the POMPU research project
The Hehemann Lab is taking part in the POMPU research project together with our partners at the Ernst-Moritz-Arndt-Universität in Greifswald, the Max Planck Institute for Marine Microbiology in Bremen and the Alfred-Wegener-Institute for Polar and Marine Research in Helgoland. The DFG research unit FOR 2406 (Proteogenomics Of Marine Polysaccharide Utilization (POMPU)) is working on mechanisms of bacterial polysaccharide utilization during marine phytoplankton blooms. Our task is the functional analysis of glycan-binding proteins and glycan transporters (Subproject A3). Link
NSERC Postdoctoral Fellowships awarded
Congratulations to Melissa Cid Robb and Craig Robb for both receiving Postdoctoral Fellowships of the Natural Sciences and Engineering Research Council of Canada (NSERC)!
Plasmids deposited at the Addgene plasmid repository
February 2017: In our recent study (Link) we described two enzymes that are used for the fast, stereo and sequence specific analysis of laminarin in marine organic matter. The respective plasmid are now available at the Addgene plasmid repository. FaGH17A is a highly specific endo-β-1,3-glucanase hydrolyzing the β-1,3 glucose backbone of laminarin (Link), whereas FbGH30 is an exo-β-1,6-glucanase that removes the β-1,6-glucose side chains (Link).
Publication in Applied and Environmental Microbiology
February 2017: Marine algae produce varieties of glycans, which fulfill diverse biological functions and fuel the carbon and energy demand of heterotrophic microbes. However, the common approach to analyze marine organic matter using acid to hydrolyze its glycans into measurable monosaccharides does not distinguish between glycans in natural samples. Stefan Becker and colleagues developed a method to selectively digest and thereby quantify laminarin in particulate organic matter by using carbohydrate active enzymes from marine Flavobacteria. The results demonstrate the potential of enzymes as toolkits for faster, stereo and sequence specific analysis of select glycans in marine organic matter. (https://doi.org/10.1128/AEM.03389-16)
