The Centre for Structural Biology (CSB) at Aarhus University, Denmark, studies the molecular and structural foundations of life in both bacteria and higher organisms. CSB investigates the three-dimensional structure of biological macromolecules, proteins and nucleic acids, by using several biophysical techniques, in particular x-ray crystallography. The facilities at the centre allow application of a wide range of techniques in molecular biology, biochemistry and biophysics.

The scientific focus at the CSB is centered around the gene expression pathway in both bacteria and higher life forms, studying essential processes of mRNA and protein biosynthesis in molecular detail. Another important focus area is the study of membrane proteins that are responsible for important transport of metabolites and small molecules across the cellular barrier.

The centre was founded in 2003 as a research centre under the Danish Research Agency (FNU), but represents 40 years of experience with biomolecular structure determination. CSB consists of nine independent but closely interacting research groups at the Department of Molecular Biology and Genetics (MBG). At the Department of Molecular Biology and Genetics, CSB is also known as the Section for Structural Biology.
