Design Notes
The observed UP elements were A-T rich. Therefore, the rational sequence modifications of Design 1 were made to preserve this feature. Nucleotides in Design 1 at positions -59, -54, and -45 were changed from G to T, A to T, and C to G, respectively. A spacer, CT, is placed between the UP element and subsequent promoters to maintain proper alignment with RNAP.
