pre-csgE RBS
RBS to follow csgBAC and precede csgEFG operon in a synthetic curli operon.
The native curli operon in MG1655 E. coli contains two divergent operons: csgBAC as well as csgDEFG. To create a synthetic curli operon, both csgBAC and csgEFG are necessary (for example, though csgA is the main subunit of the eventual fiber, csgG is responsible for fiber export out of the cell). csgD regulates csgBAC, and is thus unnecessary in a synthetic operon where both component operons are combined under the control of one promoter.
When successfully assembled in a transcriptional unit with a promoter, csgBAC, csgEFG, and a terminator, this RBS results in curli amyloid fiber production. Curli fibers constitute the main proteinaceous component of Enterobacteriaceae species such as E. coli (Barnhart & Chapman, 2006).
