TRK system potassium uptake protein CeoC; Part of a potassium transport system.

Alternative RNA polymerase sigma factor SigE; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released. Responds to heat shock and surface stress (detergent exposure). When combined with isolated core RNA polymerase from M.smegmatis is able to guide initiation from the sigB promoter. Required for full expression of sigB, and for sigB induction after detergent exposure but not after heat shock. Con [...]

Conserved protein; Binds to RNA polymerase (RNAP), stimulating and stabilizing the formation of stable RNAP promoter complexes up to 2-fold from principal sigma factor SigA-dependent but not alternative sigma factor SigF-dependent promoters. Increases the affinity of core RNAP for SigA, increasing the transcriptional activity of RNAP. Unlike the case in M.smegmatis or S.coelicolor, has no effect on rifampicin inhibition of transcription. Has no effect on E.coli RNAP. Belongs to the RNA polymerase-binding protein RbpA family.
