The Laboratory of Structural Biology was founded in 2002 as a joint laboratory of the Institute of Systems Biology and Ecology of the Academy of Sciences and the Institute of Physical Biology of the University of South Bohemia named Laboratory of High Performance Computing . The fundamental methods were the demanding computational techniques that cover a range of processes involving solving structure, interactions and dynamics of proteins and membranes up to the conformational changes of small molecules such as nucleic acids and carbohydrates. The relationship between the structure and function of the proteins and their complexes became a central research issue. Continuesly growing, the laboratory today combines methods ranging from computational and spectroscopic, to molecular biological, biochemical, and in collaboration with the Kuta Smatanova lab protein crystallisation. With its focus on molecular systems biology, the relationship between structure and function of proteins, dynamic changes related to functional processes on the level of proteins and the mutual interaction of cofactors and subunits in protein complexes the laboratory is an integral part of the new research concept of the Institute. The research approach is very complex using various methods of protein research with a synthesis of theoretical and experimental methods. Molecular dynamics, quantum chemical and semiempiric calculations of optical spectra, charge localisation or energy transfer and molecular modelling methods are combined with mostly spectroscopic and crystallographic methods and methods of protein structure determination. The laboratory has highly ambitious aims with regard to the development of new methods in molecular systems biology and its application to systems of a common interest, hot topic systems.
