Properties

The ribosome binding site (RBS) is a sequence located approximately 8-13 nucleotides upstream of the initiating AUG on mRNA, which can be precisely recognized by 16s rRNA through base complementarity [1]. This sequence promotes ribosome binding to mRNA, facilitating translation initiation. The length and base composition of the RBS sequence influence ribosome binding and translation efficiency to some extent [1]. A stronger RBS makes it easier for ribosomes to bind, thereby increasing gene expression levels, while a weaker RBS can reduce gene expression levels or only express under specific conditions.

Therefore, by replacing the RBS sequences that regulate the translation of the target protein, we can control the expression level of the target protein. We obtained a mutant of the original RBS (BBa_B0034) from the literature [2]. The RBS calculator showed a 9-fold decrease in the intensity of this mutant.
