Postdoctoral fellows are encouraged to apply for a position at Department of Biotechnology and Biomedicine (DTU Bioengineering) at the Technical University of Denmark placed in the Enzyme and Protein Chemistry group in the section of Protein Chemistry and Enzyme Technology with about 80 staff members. The employment depends on applicant’s expertise and can be for 24 months.

The work is part of a project ‘DSMADE’ (Discovery, Specificity and Mechanism of Alginate Degrading Enzymes) granted by the Independent Research Fund Denmark ! Natural Sciences.

The research will be carried out at DTU Bioengineering, DTU Compute, DTU Biosustain, Norwegian University of Science and Technology (NTNU), University of Barcelona and University of Aix-Marseille involving Bernard Henrissat, Ole Winther, Casper Wilkens, Ditte H. Welner, Carme Rovira, Finn L. Aachmann and Birte Svensson. 

Responsibilities and qualifications
Initial focus is on applying bioinformatics and developing deep learning tools to identify candidates primarily of alginate lyases in a wide range of polysaccharide lyase families by exploring biological sequence databases, gene catalogues and bacterial genomes. Identified candidates are then subjected to validation of the predictive tools by determination of three-dimensional structures and biochemical and enzymatic characterization after recombinant production. Further, selected three-dimensional structures of enzyme-oligosaccharide complexes will be subjected to computational analysis of the mechanism of action. Alginate is a marine polysaccharide composed of mannuronate and guluronate residues organized in different block structures. We aim at identifying tools for disclosing the relationship between the fine substrate specificity and the reactions at the activity sites of these diversely evolved enzymes. Additionally we shall investigate structure/function relationships of the enzyme candidates and the synergism between exo-and endo-acting enzymes with different substrate preferences using defined alginates and polyuronic acids as substrates.   


The successful candidate will benefit from being part of a multidisciplinary project advancing validated accurate annotation of the function of polyuronic acid degrading enzymes. The partners provide excellent collaborating research environments including state-of-the-art computations and data science, infrastructure and instrumentation. Alongside the DSMADE project related experimental research is pursued on alginate converting enzymes by several of the different partners. In particular at DTU Bioengineering and NTNU a number of other young scientists work on alginate converting enzymes mostly on biochemical, structural and enzymatic properties. 

Finally, even though DSMADE has no formal industrial partner we are well connected with industries working on production of alginates and oligosaccharides derived thereof for various applications in the food and pharma sectors.  

As a formal qualification, you must hold a PhD degree (or equivalent) earned no more than 4 years before the deadline for application to this advertisement.

We expect you have a solid background within bioinformatics and protein science and a good understanding of protein and enzyme structure-function relationships.

Experience with several of the below topics will be a special advantage:

  • Machine learning
  • X-ray crystallography
  • Molecular dynamics
  • CAZymes
  • Carbohydrate chemistry including on polyuronic acids
  • Enzyme mechanisms

We expect you are motivated for:

  • individual as well as team accomplishments
  • working in a multidisciplinary project
  • interacting with international research leaders and their research groups

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment.
