Newfound hijacked proteins linked to salmonella virulence
Date:8/23/2011

oy and co-authors identified the chemical nature of the modification that occurs on EF-P. This is critical because in the team's experiments, when the modified version of EF-P is absent, Salmonella doesn't spread.

Because the mechanism by which the modification occurs is unique to bacteria and this system is involved in virulence it could be a potential drug target, Ibba said.

Roy's experience and interest in this area is what drew him to UCF. His lab in the Burnett School of Biomedical Sciences at UCF will use National Institutes of Health funding to explore how some other components of the protein synthesis machinery have been hijacked to accomplish alternate cellular processes. For instance, one process utilizes parts of the protein synthesis machinery to modify components of the bacterial membrane. This mechanism increases bacterial resistance to a large spectrum of antibiotics and presents a good avenue for new drugs that could potentially alleviate or cure many infectious diseases.

"That's why I came to UCF," Roy said. "There is a good team of scientists here working in infectious diseases. There is a good opportunity to collaborate and make a difference."
