Functional reconstitution of an unusual Firmicutes σ factor into a Gram-negative heterologous host.

Canadian journal of microbiology - 1 Nov 2015

Davis Maria C, Kesthely Christopher A, Smith Logan K, Breen Jillian, MacLellan Shawn R

Abstract excerpt

Sigma (σ) factors are single-subunit proteins that reversibly bind RNA polymerase and play an important role in the transcription initiation process. An unusual 2-subunit σ factor, consisting of proteins SigO and RsoA, activates transcription from a group of related promoters in Bacillus subtilis. These 2 proteins specifically interact with each other and with RNA polymerase subunits. This system is widespread...
