What's a GeneRIF?
  1. Donor strand sequence, rather than donor strand orientation, determines the stability and non-equilibrium folding of the type 1 pilus subunit FimA.
    Title: Donor strand sequence, rather than donor strand orientation, determines the stability and non-equilibrium folding of the type 1 pilus subunit FimA.
  2. X-ray structures of all three FimA monomers at 0.89-1.69 A resolutions, reveal identical, intramolecular donor-strand complementation mechanisms. Our results also showed that the pseudo-palindromic sequences of the donor strands in all FimA proteins permit their alternative folding possibilities.
    Title: Alternative folding to a monomer or homopolymer is a common feature of the type 1 pilus subunit FimA from enteroinvasive bacteria.
  3. FimA is capable of intramolecular self-complementation via its own donor strand, as evidenced by the loss of folding competence upon donor strand deletion.

  4. Results show that pilA recombinant protein has some immunoprotection effect with the challenging of virulent strains of E. coli GH1.2.
