WebMay 26, 2024 · To confirm the basic necessity of the Ara-box the last two bases of the Ara-box were exchanged in pSVAaraFX-LacS-xylR, creating pSVAaraBox1 and pSVAaraBox2 , respectively. These single point mutations in the Ara-box nearly abolished all promoter activity and therefore show the importance of the conserved motif.

WebJul 1, 1996 · The DNA contains no obvious −10 and −35 sequences other than those at the ara PBAD promoter. Secondary polymerase binding sites have been observed near some promoters and their presence has complicated data interpretation ( 9–11). For the experiments done with ara two such sites, at positions −64 and −96, had been removed ( 1).
WebIt has also been shown that by incubating cultures with increasing submaximal (non-saturating) concentrations of arabinose, the yields of the target protein can be reproducibly increased over a greater than 100-fold range, and this finding forms the basis for advocating the use of ara promoter vectors in experiments in which fine control over the levels of a …
WebApr 3, 2014 · In practice, the term "promoter" describes the combination of the promoter (RNA polymerase binding site) and operators (response elements). Promoters are about 100 to 1000 base pairs long and found upstream of their target genes.
