The laboratory was founded in 1989.

Main investigation trends:

  • genetic engineering of microbial strains producing enzymes of nucleic acid metabolism, physical-chemical characterization of the enzymes and enzymatic production of a broad spectrum of natural and modified nucleosides and nucleotides;
  • elaboration of technologies and manufacturing PCR reagents;
  • designing sets of reagents for diagnostics of infectious diseases in humans and animals using real-time PCR technique;
  • development of technologies for enzymatic synthesis of immune-stimulating nucleic acid compounds.

Results of researh activities:

  • several dozens of hyperactive bacterial strains were engineered to produce recombinant enzymes, like nucleoside phosphorylases, proteinase K, dextran saccharase, nucleoside kinase, nucleoside mono- and nucleoside diphosphate kinase, diguanylate- and diadenylate cyclase, etc. The resulting biocatalysts were engaged in technologies of producing a wide series of compounds:
  1. modified nucleosides serving as substrates for manufacturing drugs applied in treatment of human viral and cancer diseases;
  2. cyclic 3ʹ,5ʹ-diguanylate, its arabinofuranosyl and deoxy derivatives, cyclic 3ʹ,5ʹ-diadenylate displaying potent immune-stimulating activities;
  3. highly purified natural 2ʹ-deoxynucleoside-5ʹ-triphosphates essential for conducting standard and real-time PCR;
  • in collaboration with Institute of Bioorganic Chemistry, NAS Belarus original chemical-enzymatical processes for producing superefficient antitumor drugs «Leucladin» and «Fludarabel» were developed and scaled up to industrial level;
  • the technology was elaborated for nanostructuring proteins, nucleic acids and derived components to promote their safe delivery and controlled release in target cells.
