Microbiologists at the Max Planck Institute in Marburg have investigated how a small protein enables bacteria to sensitively recognize antimicrobial peptides and effectively defend themselves. (mpg.de)
The PhoQ/PhoP signaling system, which allows bacteria to recognize small amounts of antimicrobial peptides, is controlled by the small protein MgrB and stabilized by a negative feedback mechanism: When bacteria invade the host, the PhoQ/PhoP system is activated due to the relatively low physiological magnesium concentration.
