Promoter activities in Corynebacterium glutamicum strains with deletions of genes encoding sigma factors of RNA polymerase suggested that transcription from some promoters is controlled by two sigma factors. To prove that different sigma factors are involved in the recognition of selected Corynebacterium glutamicum promoters, in vitro transcription system was applied. It was found that a typical housekeeping promoter Pper interacts with the alternative sigma factor sigma(B) in addition to the primary sigma factor sigma(A). On the other way round, the sigma(B)-dependent promoter of the pqo gene that is expressed mainly in the stationary growth phase was active also with sigma(A). Some promoters of genes involved in stress responses (P1clgR, P2dnaK, and P2dnaJ2) were found to be recognized by two stress-responding sigma factors, sigma(H) and sigma(E).
