Melville, "Sporulation and enterotoxin (CPE) synthesis are controlled by the sporulation-specific
sigma factors SigE and SigK in Clostridium perfringens" Journal of Bacteriology, vol.
Sigma factor is calculated following the multidirectional algorithm described in LaPointe [55].
Tanaka, "A response regulator Rre37 and an RNA polymerase
sigma factor SigE represent two parallel pathways to activate sugar catabolism in a cyanobacterium Synechocystis sp.
Among the set of promoters under the control of a single and the same
sigma factor, the level of transcription varies depending on the culture conditions or the growth phase.
[30] DeVries CA, Ohman DE Mucoid-to-nonmucoid conversion in alginate-producing Pseudomonas aeruginosa often results from spontaneous mutations in algT, encoding a putative alternate
sigma factor, and shows evidence for autoregulation.
These isolates carried plasmids encoding all 6 pCT regions that were investigated ([bla.sub.CTX-M-14], nikB, putative
sigma factor, rci, pilN, and pCT008-009) and when compared with pCT had identical flanking regions adjacent to [bla.sub.CTX-M-14].

sigma factors. J Bacteriol 1994;176:2773-80.
FliA is part of class II and is the
sigma factor of the flagellar system.
The bacteria's defenses are controlled by an alternative
sigma factor, a protein that acts as a switch for certain genes.
