Question

In Arabidopsis, recognition of this protein’s N-terminal domain triggers the binding of BAK1 to a sensor kinase. CsrA represses the translation of this protein, whose cytoplasmic levels are regulated by the W regulator and S chaperone members of its protein family. This protein is fused with thioredoxin in a faster alternative to conventional phage display. Sensing and recognition of this protein were originally postulated to be the exclusive purpose of Nlrc4 in the inflammasome. In mammals, this protein is directly recognized by (*) TLR5, which has led to its use as a potent adjuvant in vaccines. Bacteria like Salmonella (-5[1])or Legionella deliver this protein to the cytosol (-5[1])by type-III and type-IV secretion systems, respectively. For 10 points, name this large globular protein that is the major constituent of the whip-like (10[1])appendage (10[2])characteristic (10[2]-5[1])of (10[1])most motile (10[1])bacteria. ■END■ (10[4]0[5])
