Institute of Biotechnology

 The Team of Molecular and Cellular Biology,

headed by Dr. Jurgita Matulienė (Ph. D. in cell biology from the University
of Minnesota, USA, 2003), makes target proteins by gene cloning, expression in E.coli, insect, or mammalian cells, and chromatografic purification of large quantities of active proteins sufficient for biothermodynamic measurements of compound binding. Several projects involve the design of mutants and
truncated protein domain constructs. Live human cancer cells are cultured for the evaluation of compound anticancer activity. Dr. Vilma Petrikaitė has a Ph.D. in pharmacy and performs compound testing in mice xenografts. The team collaborates with the Department of Immunology and Cell Biology in antibody design and diagnostic markers.

The Team of Organic Synthesis,

headed by Dr. Virginija Dudutienė (Ph. D. in organic synthesis from the Vilnius University, 2005), synthesizes compounds that are designed to bind carbonic anhydrases and other drug target proteins. Compounds are designed by computer docking, molecular modeling, and comparison with naturally occurring or previously
synthesized compound functional groups. Compound identity and purity is verified by NMR and HPLC-HRMS.

The Team of Biophysics,

headed by Prof. Daumantas Matulis (Ph. D. in biochemistry, molecular biology and biophysics from the University of Minnesota, USA, 1998), measures compound binding to target proteins by isothermal titration calorimetry (ITC), fluorescent thermal shift assay (DSF, ThermoFluor®), pressure shift assay (PSA), and conventional enzyme inhibition methods. The team determines intrinsic Gibbs free energies, enthalpies, entropies, heat capacities and volume of binding and measures protein stability in the presence of various excipients.

The Team of Molecular Modelling,

headed by Dr. Vytautas Petrauskas (Ph. D. in physics from the Vilnius University, 2008), is responsible for the application of computational methods, database management, in silico docking of large compound libraries and the analysis of X-ray crystal structures of synthetic compound – protein complexes solved in collaboration with Dr. Saulius Gražulis group at the Department of
Protein – DNA interactions. Molecular modelers collaborate with the Department of Bioinformatics and use their methods to model protein structures that are not solved by X-ray crystallogphy. The group, together with several collaborating scientists is developing the software that estimates the energies of compound binding to a protein when only the crystal structure of the free protein is available.

The Team of Amyloid Research.

Recently a new team has started upon the return of Dr. Vytautas Smirnovas (Ph. D. from the Technical University of Dortmund, 2007) to Lithuania in 2011. The main interests and research of his team lie in the protein aggregation and amyloidogenesis that are involved in a number of diseases, including such neurodegenerative disorders as Alzheimer’s and Parkinson’s.
