Nonetheless these tags might alter enzyme specificity and activity, therefore in functional assays it is recommended to use authentic or native proteins. Several ubiquitin fusion systems have been developed for E. coli-based recombinant protein expression that provide high levels of expression, with simple purification, and allow the production of various proteins with authentic N-terminus for subsequent applications. Results: In the present research, we describe an ubiquitin fused bacterial biosynthetic system (pUbiq) for the production of the native Second mitochondria-derived activator of caspases (SMAC) recombinant protein. Using this system, the recombinant protein is expressed with an ubiquitin-decahistidine fusion partner, then purified from the cell-forming proteins by affinity chromatography. The fusion partner is then removed by proteolytic digestion, resulting the native structure of the recombinant protein without unnecessary amino acid residues. Following proteolysis, another affinity chromatography method is used to separate the native protein from the fusion partner and the proteolytic enzyme. The folding of the protein of interest was verified by a pull-down assay. Conclusions: Based on our results, the presented pUbiq system was successfully applied in the production of native SMAC recombinant protein, where the affinity tag required for purification was completely removed. Our study suggests that the ubiquitin-fusion technology will be useful for enhancing expression and purification of native and authentic proteins for structural and functional studies as well as for therapeutic uses.

Mapping up critical apoptosis regulators is a strategy for the development of new therapies [1, 2].Present work highlights optimization of heterologous expression conditions for the X-linked inhibitor of apoptosis protein (XIAP). Genes of target protein containing pGEX-4T vector was transformed in chemically competent E. coli Rosetta (TM)(DE3)pLysS cells. The recombinant construct contained a glutathione S-transferase (GST) fusion partner, which assured the purification of the protein by affinity chromatography. In the next step we examined the growth dynamics of the expression culture in M9 minimal medium, meanwhile we also determined the appropriate time of induction. Following this we carried out the optimization of expression, examining the expression's effectiveness under different conditions. On the basis of these fermentation experiments the target protein expression was the most prominent at 18 degrees C with 0.2 mM IPTG induction for 12 hours. During large scale fermentation experiments, we followed the optical density (OD), dry cell weight and substrate utilization. Finally, recombinant protein expression inhancement in the presence of 3% ethanol was successfully achieved in bioreactor. In this case the target protein was expressed in inclusion bodies, therefore solubilisation and refolding is necessary.}, keywords = {Optimization; Ethanol; BIOREACTOR; heterologous expression; XIAP}, year = {2019}, eissn = {2065-9520}, pages = {101-110} } @CONFERENCE{MTMT:31356181, title = {Nekroptózist moduláló humán fehérjék bioszintézise}, url = {https://m2.mtmt.hu/api/publication/31356181}, author = {Salamon, Pál Attila and Nagy, Katalin and Kovács, Zita and Albert, Beáta and Miklóssy, Ildikó and Lányi, Szabolcs and Orbán, Csongor Kálmán}, booktitle = {XXIV.
