Biological Chemistry

Biological Chemistry is a discipline that combines chemical and biological sciences. The aim is to understand at molecular level the structures and functions of biomolecules that are involved in complex biological processes such as human diseases or photosynthesis and how these processes can be manipulated. In our interdisciplinary research we employ molecular biology, biochemical, chemical, crystallographic, biophysical, spectroscopic, theoretical and multi-variable data analysis techniques.

Specific research areas include infectious disease and discovery of antimicrobial agents, processes of protein folding and misfolding in health and disease, natural and artificial photosynthesis, protein structure and function, biosensors, medical diagnostics, and biofuel cells. We actively develop various theoretical and data analysis tools and spectroscopic and spectrometric techniques.

Henrik AnttiThe research project focuses on a combination of metabolomics and chemometric bioinformatics for studying metabolic processes, mainly in humans. The aim is to develop methods for detection of biomarker patterns for facilitated diagnosis and increased mechanistic understanding. The methods are being applied to answer important questions in human health and disease with special emphasis on cancer, infection, diet & exercise and neurodegeneration.

Backman, Lars

Lars BackmanMany processes, if not all, that occur in our cells, such as muscle contraction, fertilization, movement of cilia, transport in nerves, are all dependent on a proper functioning cytoskeleton.
Several sever diseases, such as Alzheimers and Parkinsons depend on changes in the neuron's cytoskeleton. We are studying spectrin and α-actinin, in this complicated system to understand how spectrin interact with the plasma membrane and other proteins in the cell as well as the role thses proteins play in cell survival.

Hedberg, Christian

Christian HedbergOur research is centered on the chemistry between host cells and pathogens during infection. We are using chemical tools generated by classical organic synthesis as well as genetic methods to dissect mechanisms of host-pathogen interactions in an interdisciplinary way. In the long run, the generated knowledge will lead to improved methods to address intracellular pathogens.

Johansson, Lennart B-Å

Lennart B-Å JohanssonThe project aims at a molecular-level development and application of electronic energy transport processes for structural insights into complex systems, such as proteins, lipid membranes, as well as protein-membrane systems. One major goal is to develop spectroscopic tools that complement NMR- and X-ray methods. The applications, e.g. photosynthesis, deal with general questions of protein structure and functioning under in vitro and cell-like conditions.

Dan Johnels I am mostly involved in structure determination of fullerene derivatives, such as hydrogenated fullerenes, in cooperation with researchers at the Physics Department at Umeå University.  In addition, we have recently started a project aimed at the development of chromatographic materials for separation of fullerene derivatives, as this is a major obstacle due to the vast number of isomers that can be formed in the derivatization of fullerenes.

Nam, Kwangho

Kwangho Nam In my lab, we develop and apply computational and theoretical methods with the goal to investigate chemical and physical problems presented by biomolecular systems. Our current developmental efforts focus on advancing our ability to simulate protein systems where chemistry is linked with large scale protein conformational dynamics and computation of corresponding free energies. The application part involves, but not limited to, kinases, ATP hydrolases, and DNA repair enzymes. These biomolecules present unique set of challenges that experiments are unable to address, while theory can provide atomic level understanding.

Schröder, Wolfgang

Wolfgang SchröderChaperones are proteins that assist the proper folding of newly synthesized proteins. They are important in preventin misfolding and aggregation in the cell and therfore often stress-induced proteins. The thylakoid lumen from plants contains a specific set of chaperones. Our aim is to understand the chaperone network in plants to be able to better prevent protein misfold and to be able to understand how toxic protein aggregates are formed in both plants and humans. Our experimental approaches combine genetics, biochemistry and biophysics.

Westlund, Per-Olof

Per-olof WestlundThe theoretical chemical research describes molecular dynamic processes in chemistry from a fundamental physical basis. We derive equations that are used to interpret the experimental results primarily obtained from NMR and ESR and light spectroscopy. Water is of particular interest and we examine how its properties change in the limited space such as in Zeolite , in cellulose fibers or  at the interface between biomolecules and  water. General science seeks to reduce the complexity of biosystems to various molecular processes and we must also ask what is missed in this reductionism?
