We have previously developed a general method based on the statisticaltechnique of discriminant analysis to predict splice junctionsin eukaryotic mRNA sequences [Nakata, K., Kanehisa, M. and DeLisi,C. (1985) Nucleic Acids Res., 13, 53275340]. In orderto evaluate further applicability of this method, we now analyzethe promoter region of Escherichia coli sequences. The attributesused for discrimination include the accuracy of consensus sequencepatterns measured by the perceptron algorithm, the thermal stabilitymap, the base composition and the Calladine-Dickerson rulesfor helical twist angle, roll angle, torsion angle and propellertwist angle. When applied to selected E. coli sequences in theGenBank database, the method correctly identifies 75 % of thetrue promoter regions.

ACE1 transcription factor produced in Escherichia coli binds multiple regions within yeast metallothionein upstream activation sequences. 总被引:10,自引:6,他引:4 下载免费PDF全文
The ACE1 protein of Saccharomyces cerevisiae was expressed as a trpE-ACE1 fusion protein in Escherichia coli and shown to bind CUP1 upstream activation sequences at multiple regions in a copper-inducible manner. These binding sites contain within them the sequence 5'-TC(T)4-6GCTG-3', which we propose constitutes an important part of the ACE1 consensus recognition sequence. 相似文献
