EXAMPLE

Fusion DNA Polymerase NeqSSB-Bst

[0085] Fusion DNA polymerases NeqSSB-Bst were obtained by fusion of three various Bst polymerases with NeqSSB protein at polymerase N-end using the linker consisting of six amino acids of the following sequence: Gly-Ser-Gly-Gly-Val-Asp. The sequences of the three variants of fusion DNA polymerase are presented in the figure SEQ. 1-3 (amino acid sequences) and SEQ. 4-6 (nucleotide sequences). DNA polymerases were obtained in the laboratory scale in the prokaryotic system based on Escherichia coli bacteria.

Preparation—Example 1

[0086] First step of the DNA polymerase preparation includes the expression of the gene encoding the enzyme in the optimised conditions in microbiological shaker: growth temperature—30° C., incubation time of the medium after induction—3 to 20 h, inductor concentration—0.1 to 1 mM IPTG. In the protein purification process the obtained cell lysate is subjected to the disintegration using ultrasound and removal of the DNA genomic contamination using dsDNase. Thanks to the presence of the oligohistidine domain, the second purification step utilises the metal affinity chromatography with His-Trap beads (FIG. 1). The next steps cover triple dialysis until obtaining the conditions which provide the stability for DNA polymerase (10 mM Tris-HCl pH 7.1, 50 mM KCl, 1 mM DTT, 0.1 mM EDTA, 50% Glycerol, 0.1% Triton X-100), gel filtration, and densification of the preparation. All the processes were conducted in 4° C. The purity of the obtained proteins was tested using SDS-PAGE electrophoresis, and the number of units for the obtained preparation was determined using EvaEZ Fluorometric Polymerase Activity Assay Kit Biotium (USA) according to the definition of unit: 1 activity unit [1 U] is the amount of DNA polymerase which can incorporate 10 nmol of nucleotides in 30 min in its optimum operation temperature 65° C. (FIG. 2). 1 litre of the laboratory scale culture provides approx. 5 mg of purified preparation with the activity of approx. 10 000 U, what enables the respective number of amplification reactions.

Preparation—Example 2

[0087] Expression of the gene encoding the fusion DNA polymerase was conducted in the conditions providing appropriate oxygenation of the liquid culture in the temperature of 28° C. Logarithmic-phase cultures were induced using IPTG with the amount providing the protein expression—IPTG in the range of 1 mM to 0.1 mM and incubation of 3 to 20 hours (FIG. 3). After that the cell lysate was mechanically disintegrated and purified using metal affinity chromatography and ion-exchange chromatography. The obtained fusion DNA polymerases were subjected to the dialysis for the storage conditions (10 mM Tris-HCl pH 7.1, 50 mM KCl, 1 mM DTT, 0.1 mM EDTA, 50% Glycerol, 0.1% Triton X-100) and provided in the concentration of 1 U/μL based on the commercial EvaEZ Fluorometric Polymerase Activity Assay Kit of Biotium (USA) according to the definition of unit.

Preparation—Example 3

[0088] An efficient expression of the gene encoding the polymerase Bst fused with NeqSSB protein was obtained in culture in 37° C. and induction of IPTG in range of 1 mM to 0.1 mM for 3 to 20 hours (FIG. 3). Centrifuged and mechanically disrupted cell lysate was purified using chromatographic techniques (metal affinity chromatography and ion-exchange chromatography), suspended in the formulation buffer (10 mM Tris-HCl pH 7.1, 50 mM KCl, 1 mM DTT, 0.1 mM EDTA, 50% Glycerol, 0.1% Triton X-100) and provided in the concentration of 1 U/μL. The amount of DNA units was defined based on the definition of unit using the EvaEZ Fluorometric Polymerase Activity Assay Kit of Biotium (USA).

[0089] The comparative analysis of the properties of the enzymes being the subject of the invention with the reference DNA polymerase Bst have shown that the presence of an additional DNA-binding NeqSSB protein has a positive impact on the DNA polymerase properties. The thermostability of the all obtained fusion variants of the DNA polymerases in comparison with the reference DNA polymerase Bst was increased by approx. 20% (FIG. 4). Moreover, the DNA polymerases in fusion with NeqSSB protein shown the threefold increase of processivity (FIG. 5). The fusion DNA polymerases tolerate the concentration of clinical (lactoferrin, heparin) and environmental (humic acid, soil, polyphenols) inhibitors in the reaction mixtures increased even by several dozen of times comparing with the reference polymerase (FIG. 6). The fusion DNA polymerases exhibited increased sensitivity by several times and thus increased affinity to the DNA matrix comparing with the reference DNA polymerase Bst.
