Role of the Porphyromonas gingivalis extracytoplasmic function sigma factor, SigH.

Molecular oral microbiology - 1 Jun 2012

Abstract excerpt

Little is known about the regulatory mechanisms that allow Porphyromonas gingivalis to survive in the oral cavity. Here we characterize the sigma (σ) factor SigH, one of six extracytoplasmic function (ECF) σ factors encoded in the P. gingivalis genome. Our results indicate that sigH expression is upregulated by exposure to molecular oxygen, suggesting that sigH plays a role in adaptation of P. gingivalis to...
