Protective Switch Used By Salmonella During Infection Suggests Metabolic Changes That Researchers Might Exploit To Fight Systemic Illness
For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appears to be used by the bacteria to respond to changes in the environment during infection and might protect it from harm, researchers report this week online in the Proceedings of the National Academy of Sciences Early Edition. S-thiolation protects proteins from irreversible chemical changes when a cell is stressed...
