The essential activities of the bacterial sigma factor [PDF]

Canadian Journal of Microbiology, 2017
Transcription is the first and most heavily regulated step in gene expression. Sigma (σ) factors are general transcription factors that reversibly bind RNA polymerase (RNAP) and mediate transcription of all genes in bacteria. σ Factors play 3 major roles in the RNA synthesis initiation process: they (i) target RNAP holoenzyme to specific promoters ...

System-Level Analysis of Transcriptional and Translational Regulatory Elements in Streptomyces griseus

Frontiers in Bioengineering and Biotechnology, 2022
Bacteria belonging to Streptomyces have the ability to produce a wide range of secondary metabolites through a shift from primary to secondary metabolism regulated by complex networks activated after vegetative growth terminates.

An alternative sigma factor governs the principal sigma factor in Streptomyces griseus [PDF]

Molecular Microbiology, 2013
SummaryIn bacteria, the RNA polymerase holoenzyme comprises a five‐subunit core enzyme and a dissociable subunit, sigma factor, which is responsible for transcriptional initiation. The filamentous bacterium Streptomyces griseus has 52 sigma factors, including one essential ‘principal’ sigma factor (σHrdB) that is responsible for the transcription of ...

Mycobacterial SigA and SigB Cotranscribe Essential Housekeeping Genes during Exponential Growth

mBio, 2019
Mycobacterial σB belongs to the group II family of sigma factors, which are widely considered to transcribe genes required for stationary-phase survival and the response to stress.

The Potential Link between Thermal Resistance and Virulence in Salmonella: A Review

Frontiers in Veterinary Science, 2017
In some animals, the typical body temperature can be higher than humans, for example, 42°C in poultry and 40°C in rabbits which can be a potential thermal stress challenge for pathogens. Even in animals with lower body temperatures, when infection occurs,
