    Jessica K Kajfasz
    Center for Oral Biology, University of Rochester Medical Center, Box 611, 601 Elmwood Ave, Rochester, NY 14642, USA
    J Bacteriol 192:2546-56. 2010
    ..Given the high degree of conservation between Spx proteins of low-GC gram-positive bacteria, these results are likely to have broad implications...

  4. ncbi The Spx regulator modulates stress responses and virulence in Enterococcus faecalis
    Jessica K Kajfasz
    Center for Oral Biology, University of Rochester Medical Center, Rochester, New York, USA
    Infect Immun 80:2265-75. 2012
    ..Collectively, our results show that Spx is a major stress gene regulator and is implicated in the pathophysiology of E. faecalis. The relationship of Spx to other oxidative stress regulators is also discussed...
