Promoter selectivity of Escherichia coli RNA polymerase: effect of base substitutions in the promoter -35 region on promoter strength.
A set of 18 variant lac UV5 promoters was constructed, each carrying a single base substitution within the -35 region (nucleotide positions from -36 to -31 relative to the transcription start site). Using truncated DNA fragments carrying these variant promoters and purified Escherichia coli RNA poly...
