- Comparison of putative H. elongata promotor elements and E. coli consensus sequences for σ70 and rpoH dependent promoters: The putative σ70 ectA promoter was found by Göller [24], and recent umpublished Data from our group). Consensus sequences are according to the review of Wösten [23]. Bases identical to the consensus sequence are given in upper case, differing bases in lower case. Note that the undefined nucleotide (n) in the rpoH consensus and its equivalent are also given in lower case.
