Discovery yields master regulator of toxin production in staph infections

An enzyme that regulates production of the toxins that contribute to potentially life-threatening Staphylococcus aureus infections has been discovered by researchers. The enzyme allows Staphylococcus aureus to use fatty acids acquired from the infected individual to make the membrane that bacteria need to grow and flourish. The results provide a promising focus for efforts to develop a much-needed new class of antibiotics to combat staph and other Gram-positive infections.
