Design, construction and characterization of a set of insulated bacterial promoters

Nucleic Acids Res. 2011 Feb;39(3):1131-41. doi: 10.1093/nar/gkq810. Epub 2010 Sep 15.


We have generated a series of variable-strength, constitutive, bacterial promoters that act predictably in different sequence contexts, span two orders of magnitude in strength and contain convenient sites for cloning and the introduction of downstream open-reading frames. Importantly, their design insulates these promoters from the stimulatory or repressive effects of many 5'- or 3'-sequence elements. We show that different promoters from our library produce constant relative levels of two different proteins in multiple genetic contexts. This set of promoters should be a useful resource for the synthetic-biology community.
