Abstract:
An approach was developed in controlling the expression ratio of two genes encoded in DNA by inserting a terminator sequence between the two genes. Escherichia coli ribosomal RNA operon T1 terminator, or E. coli tryptophane attenuater was introduced between two green fluorescent protein (GFP) mutants: ultraviolet-optimized mutant (GFPuv: F99S, M153T, V163A) and blue-shifted mutant (BFP: F64L, S65T, T145F). The ratio of the fluorescence intensity of BFP to GFPuv after transcription and translation reflected the termination efficiency of the transcriptional termination activity of the inserted terminator.

Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
