The relationship between sigma (sigma) and delta (delta) factors of Bacillus subtilis RNA polymerase has been analyzed during initiation of RNA synthesis. When core enzyme (E) containing delta factor (E delta) binds to DNA, the delta factor is released with the formation of an E-DNA complex. The addition of sigma to the E-DNA complex results in the formation of a stable E sigma-DNA complex which can synthesize RNA upon addition of nucleoside triphosphates. Sigma factor, significantly, is not released from the core during RNA synthesis. These results suggest that delta and sigma factors can act sequentially during initiation of RNA synthesis with delta acting as a DNA recognition factor and sigma acting as an initiation factor. The results do not preclude the possibility that E sigma can initiate RNA synthesis correctly since E sigma alone can bind to DNA and initiate RNA synthesis. 相似文献

The nucleotide sequence of a 2.14 kb fragment of Bacillus subtilis DNA containing the citG gene encoding fumarase was determined using the dideoxy chain termination method. The citG coding region of 1392 base pairs (464 codons) was identified, and the deduced Mr (50425) is in good agreement with that of the protein identified from expression in Escherichia coli maxicells. There is no sequence homology between the B. subtilis and E. coli fumarases. Overlapping potential promoter sequences have been identified for sigma 28, sigma 37 and sigma 55 RNA polymerase holoenzymes. The DNA fragment also contains the proximal part of the gerA locus, responsible for L-alanine-sensitive spore germination. 相似文献
