Expression of the secondary sigma factor sigmaX in Streptococcus pyogenes is restricted at two levels.

Journal of bacteriology - 1 Aug 2003

Opdyke Jason A, Scott June R, Moran Charles P

Abstract excerpt

Secondary RNA polymerase sigma factors in many bacteria are responsible for regulating a vast range of processes including virulence. A protein (sigma(X)) in the gram-positive human pathogen Streptococcus pyogenes (the group A Streptococcus or GAS) was recently shown to function in vitro as a sec...
