Abstract
Transkripcijski faktor QacR regulatorni je protein povezan s mehanizmom rezistencije bakterije Staphylococcus aureus na mnoge antibiotike, dezinficijense te kvaterne amonijeve soli. Ovaj represorski protein kontrolira ekspresiju gena qacA. Ekspresijom gena qacA povećava se koncentracija proteina QacA odgovornog za mehanizam rezistencije. Ovaj protein predstavlja „pumpu“ koja iz stanice izbacuje toksične spojeve. Upravo rezistencija na mnoge antibiotike te velika rasprostranjenost meticilin rezisentnog S. aureus (MRSA) potaknula je veliki interes za istraživanje ovih proteina. U ovom radu plazmid s ukloniranim genom qacR ugrađen je u kompetentne stanice Escherichia coli. Eksprimirani QacR protein pročišćen je afinitetnim kromatografijom te vizualiziran na poliakrilamidnom gelu.
Abstract (english)
The transcription factor QacR is a regulatory protein associated with the mechanism of resistance of Staphylococcus aureus to many antibiotics, disinfectants, and quaternary salts. This repressor protein controls the expression of the qacA gene. Expression of this gene increases the concentration of QacA protein responsible for the resistance mechanism. This protein is a "pump" that expels toxic compounds from the cell. It is the resistance to many antibiotics and the high prevalence of methicillin-resistant S. aureus (MRSA) that has prompted great interest in research of these proteins. In this work, a plasmid containing qacR gene was inserted into competent Escherichia coli cells. The expressed QacR protein was purified by affinity chromatography and visualized on a polyacrylamide gel.
