Eukaryotic promoters drive gene expression in Escherichia coli.
Eight eukaryotic promoters have been tested for their activity in vivo in Escherichia coli. The rat beta-actin, rat amylase, rat chymotrypsin B, mouse metallothionein I, rat insulin I, human insulin, Rous sarcoma virus long terminal repeat (RSV LTR) and hepatitis B viral precore promoter activities were measured by using the bacterial chloramphenicol acetyltransferase coding sequences as the re...
متن کاملCommon DNA structural features exhibited by eukaryotic ribosomal gene promoters.
Nucleotide sequences of DNA regions containing eukaryotic ribosomal promoters were analysed using strategies designed to reveal sequence-directed structural features. DNA curvature, duplex stability and pattern of twist angle variation were studied by computer modelling. Although ribosomal promoters are known to lack sequence homology (unless very closely related species are considered), invest...
متن کاملCharacterization of Eukaryotic Core Promoters Based on Nonlinear Dimensionality Reduction
Characterization and identification of eukaryotic promoter is important for the gene prediction and genome annotation. In this paper, we study the structural characteristics of the core promoters in several eukaryotes through a series of DNA physicochemical properties and adopt a method that combines the alignment and average of multiple promoters and the nonlinear dimensionality reduction tech...
متن کاملNucleotide patterns aiding in prediction of eukaryotic promoters
Computational analysis of promoters is hindered by the complexity of their architecture. In less studied genomes with complex organization, false positive promoter predictions are common. Accurate identification of transcription start sites and core promoter regions remains an unsolved problem. In this paper, we present a comprehensive analysis of genomic features associated with promoters and ...
متن کاملNucleosome formation potential of eukaryotic DNA: calculation and promoters analysis
MOTIVATION A rapid growth in the number of genes with known sequences calls for developing automated tools for their classification and analysis. It became clear that nucleosome packaging of eukaryotic DNA is very important for gene functioning. Automated computer tools for characterization of nucleosome packaging density could be useful for studying of gene regulation and genome annotation. ...
