Projects:

  • Development of methods for protein structure determination based on low-resolution experimental data is our current focus. We collaborate on several complementary projects with various structural biologists - theoreticians and experimentalists: Dr. Matthias Bochtler (IIMCB, Warsaw, Poland), Andrzej Kolinski (Univeristy of Warsaw, Poland), Prof. Alan Friedman (Purdue Univeristy, W.Lafayette, IN, USA), Dr. Chris Bailey-Kellogg (Darmouth College, USA).
  • Modeling and experimental validation of structure predictions for restriction enzymes and related nucleases. A combination of fold recognition and homology modeling techniques is used to predict the overall fold and identify catalytic and DNA-binding residues of various REases. Site-directed mutagenesis, cross-linking, and biophysical methods for low-resolution structural characterization are employed to validate the models. Some of the experiments are analyzed in house, others in collaboration or by collaborators: Prof. Alfred Pingoud (Justus-Liebig Universitaet, Giessen), Prof. Valakunja Nagaraja and Prof. D.N.Rao (Indian Institute of Science, Bangalore), Dr. Alexander Solonin (Russian Academy of Sciences, Puschino, Russia), Prof. Jacek Otlewski (Univeristy of Wroclaw, Poland)
  • Discovery of novel human DNA repair enzymes using bioinformatics is a collaborative project initiated by Prof. Ashok S. Bhagwat (Wayne State University, Detroit, MI, USA), which aims at identification and characterization of novel human DNA repair enzymes in silico, in vitro and in vivo.
  • Engineering of DNA methyltransferases This project is focused on bioinformatics-guided engineering of structures and functional properties of DNA MTases (different permutations, substrate specificities and mechanisms of the enzymatic reaction). This project is carried out in collaboration with Dr. Monika Radlinska (Institute of Microbiology, University of Warsaw, Poland) and Dr. Saulius Klimasauskas (Institute of Biotechnology, Vilnius, Lithuania).
  • RNA methyltransferases - the evolution of structure-function relationships in RNA MTases is studied by combination of theoretical and experimental approaches. Novel RNA modification enzymes are predicted using bioinformatics tools and characterized experimentally. Key collaborators: Dr. Bruno Lapeyre (CNRS, Montpellier, France), Dr. Henri Grosjean (CNRS, Gif-sur-Yvette, France), Dr. Louis Droogmans (University of Bruxelles, Belgium), Dr. James Anderson (Marquette University, Milwaukee, WI, USA), Dr. Kent Redman (Indiana University School of Medicine, Fort Wayne, IN, USA), Prof. David Campbell (UCLA, CA, USA)
  • Classification and evolution of S-adenosylmethionine-dependent methyltransferases is a collaborative project with Drs. Eugene Koonin and L. Aravind (NCBI, NIH, Bethesda, USA) aiming at detailed classification of the MTase superfamily in the evolutionary and functional context.
  • Mechanism of transgene integration and expression in crop plant plastids is a collaborative project headed by Prof. John Gray (University of Cambridge, UK). The aim of the project is to characterize the mechanisms of several key stages of plastid transformation and foreign gene expression in different plastid types in tobacco, tomato and potato. The focus of our group is to use bioinformatics to identify genes and proteins involved in transgene integration and marker gene excision via homologous recombination, regulation of gene expression, and protein degradation in different plastid types.
