pneumococcal autolysins are enzymes involved in cell wall turnover and cellular division physiologically. they have been found to be involved in the pneumococcus pathogenesis. the aim of this study was to identify the autolytic activity of spr1754 as a novel protein of streptococcus pneumoniae . moreover, the binding of the recombinant protein to plasma proteins was also determined. the spr1754...

Recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. Genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. Differed methods for protein purification are categorized, based on cast, quality, Easy work and side effect of protein. In this article, we are investigating his His-tag protein pu...

Aeromonas hydrophila is a gram-negative bacterium which associated with gastrointestinal diseases and septicaemia. This pathogenic bacterium has several virulence factors ranging from pili to the excreted protein which called (Aerolysin) with minor and major effects, respectively. Additionally, Aeromonas hydrophila is a widely distributed bacterium that commonly causes ulcers in cyprinid fish s...

In recent years, the number of recombinant proteins used for therapeutic applications and industry has increased dramatically. Recombinant proteins are produced in many host organisms (microbial, insect, plant and mammalian cells). There are many factors to consider when choosing the optimal system for protein expression and purification including the mass, purity or solubility of the recombina...

objective: bone morphogenetic protein-7 (bmp-7) is a multifunctional growth factor predominantly recognized for its osteoinductive properties. due to the high cost of this protein, the availability of bmp-7 for treatment is limited. the heterologous production of recombinant hbmp-7 has been performed in a number of expression systems. in this study a novel form of bmp-7 was expressed in eukaryo...
