urrent Research Activities and Recent Achievements:

Molecular dynamics simulations of proteins.

Molecular dynamics simulation (MD) is a very important approach of structural bioinformatics due to the possibility of modeling of proteins and their complexes in solution. However, MD simulations are computationally very expensive and usually require a high processing power and huge storage space for trajectories. Grid computing is a very promising approach in order to encounter the limits of computational power of long MD simulations. Recently, in our department an all-atom model of full-length Hs tyrosyl-tRNA synthetase (TyrRS) was developed [1]. Long 100 ns MD simulations in grid of HsTyrRS (Fig. 1A). Domain binding interfaces also revealed the formation of H-bonds between ELR cytokine motif in TyrRS and its protection by C-module (Fig. 1B) [1].

Virtual laboratory MolDynGrid.

MolDynGrid virtual laboratory ( was established for interdisciplinary studies in computational structural biology and bioinformatics (Fig. 2). The main objective of MolDynGrid project was to provide an effective infrastructure for automation of MD simulatons and trajectory analysis in Grid environment. Since 2013 Virtual Organization moldyngrid is a part of European Grid infrastructure and utilize LRZ Linux cluster resources in Germany (Fig. 2).

MolDynGrid usually utilizes computing elements (CE) of 8 clusters and storage elements (SE) of 2 clusters that correspond to ~2500 CPUs and ~100 TBytes of disk space, respectively)
MD simulations of HsTyrRS mutants associated with Charcot-Marie-Tooth disease.

Several missence mutations G41R, E196K and 153-156delVKQV in were identified in families with CMT disease. MD simulations of CMT HsTyrRS mutants were performed in 100 ns time interval using MolDynGrid virtual laboratory services. A local β-sheet formation was observed in Rossmann fold insertion region in all 3 mutants (Fig. 3). Dispersion of CMT mutations in HsTyrRS could be understood in terms of long-range structural effects on dimer interface.

Solution structure of EMAP II cytokine.

Solution structure of a novel EMAP II cytokine was determined by multidimentional NMR spectroscopy in collaboration with Institute of Biochemistry and Biophysics in Warsaw (Fig. 4). Solution structure of EMAP II cytokine revealed more exposed cytokine motif at N-terminal β-strand and highly flexible RNA binding surface.

Nanocomposite antitumor complexes of of EMAP II cytokine.

Fundamentals of a new technology of antitumor of EMAP II cytokine production were developed in our department. EMAP II cytokine revealed antitumor activity on the growth of carcinoma of human prostate (Patent of Ukraine #33215). A novel nanocomposite complexes of EMAP II cytokine were proposed as novel anticancer drug (Patent of Ukraine #64374).
