Sequence coding for Sup35 with a N-terminal CsgA signal sequence for amyloid export This part uses the BBa_J23104 and has been inserted into the pSB1C3 backbone. The design includes the bipartite csgA signal sequence that targets the protein to the Sec-export pathway and subsequently to the curli export pathway via interaction with csgG (Sivanathan and Hochschild, 2012; Sivanathan and Hochschild, 2013). Sup35-NM is derived from the yeast prion protein Sup35p and excludes the C-terminal domain with the N-terminal domain allowing self-assembly of functional amyloid (Frederick et al., 2014; Glover et al. 1997). This has previously been discussed by Tessier and Lindquist (2009) who show that two beta-sheets bond together in a self-complimenting ‘steric zipper’ that excludes water, leaving a highly stable parallel beta-sheet with one molecule every 4.7 Angstroms. The particular advantage of using Sup35-NM is that in its native state Sup35p has two functional domains, the N and C terminal, separated by the highly charged M domain (Frederick et al., 2014; Glover et al. 1997; Wickner et al., 2007) allowing the fusion of a new functional domain.
