Identification of an UP element consensus sequence for bacterial promoters.
The UP element, a component of bacterial promoters located upstream of the -35 hexamer, increases transcription by interacting with the RNA polymerase alpha-subunit. By using a modification of the SELEX procedure for identification of protein-binding sites, we selected in vitro and subsequently screened in vivo for sequences that greatly increased promoter activity when situated upstream of the...

متن کاملConsensus sequence for Escherichia coli heat shock gene promoters.
We have identified promoters for the Escherichia coli heat shock operons dnaK and groE and the gene encoding heat shock protein C62.5. Transcription from each promoter is heat-inducible in vivo, and each is recognized in vitro by RNA polymerase containing sigma 32, the sigma factor encoded by rpoH (htpR) but not by RNA polymerase containing sigma 70. We compared the sequences of the heat shock ...
متن کاملAnalysis of consensus sequence patterns in Giardia cytoskeleton gene promoters.
Protein-coding genes in the ancient eukaryote Giardia lamblia lack typical promoter consensus elements. We have analysed the immediate 5' flanking sequences of seven genes of related function (structural cytoskeleton proteins) to identify shared DNA motifs that might have a role in transcription initiation. Transcription start sites for five genes have been determined previously. Genomic mappin...
