Specificity of promoter consensus sequences in Escherichia coli chromosome
Nucleic Acids Symposium Series
|January 1, 1991
Abstract:
Conservativeness of promoter-like sequences in transcribed and non-transcribed strands for polycistronic and monocistronic transcriptional units in Escherichia coli is investigated with chi 2-statistics. The results show that according with the degree of similarity to the consensus sequence (TTGACA--TATAAT), differences of frequencies with the theoretical one change from plus to minus.
