FIELD: chemistry.

SUBSTANCE: invention relates to biotechnology and a method of producing recombinant spider-web proteins of orb-weaving spiders in yeast cells, fused proteins containing spider-web recombinant protein sequences of orb-weaving spiders, recombinant DNA encoding fused proteins, yeast host cells and expression vectors used to realise the method, as well as producer strains of recombinant proteins of orb-weaving spiders. The method involves constructing an expression vector containing a DNA sequence encoding recombinant spider-web proteins of orb-weaving proteins, fused with a sequence which encodes ubiquitin or an ubiquitin-lie protein SUMO of yeast Saccharomyces cerevisiae, which occupies the N-terminal position in the fused protein relative the recombinant spider-web protein, transformation of yeast cells with the obtained expression vector and expression of orb-weaving spider web protein in the transformed cells.

EFFECT: method increases production of recombinant spider-web protein during accumulation thereof in yeast cells in a water-soluble fraction in form of a protein which does not contain a hybrid component.
