Abstract RU 2435858 C2

FIELD: medicine.

SUBSTANCE: invention refers to recombinant plasmid DNA pER-Hir coding a hybrid protein capable to autocatalytic breakdown to form [Leul, Thr2]-63-desulphatohirudin, to Escherichia coli to an ER2566/pER-Hir strain - a producer of said protein and a method for producing genetically engineered [Leu 1, Thr2]-63-desulphatohirudin. The presented recombinant plasmid DNA consists of the SapI/BamHI fragment of DNA plasmid pTWIN-1 containing a promoter and a terminator of T7-RNA-polymerase transcription, an amplifier of phages T7 gene 10 translation, β-laktamase (Ap) gene, modified mini-intein Ssp DnaB gene, with an integrated sequence of a chitin-binding domain, and the SapI/BamHI-fragment of DNA containing a sequence of a gene of recombinant [Leul, Thr2]-63-desulphatohirudin-1 containing β-laktamase (Ap) gene as a genetic marker, and unique recognition sites of restriction endonucleases located at the following distance to the left from the site BamHI: Nrul - 186 base pairs, Ndel - 594 base pairs, Xbal - 882 base pairs, EcoRV - 2913 base pairs, Hpal - 2966 base pairs.

EFFECT: inventions allow producing said compound which is used as a drug applied to prevent blood hypercoagulation.
