FIG. 5.

(A) Swarming of the fliH null mutant transformed with pTrc99A-based plasmids encoding 10-amino-acid deletion derivatives of FliI. Plates were incubated for 5 h at 30°C. V, vector. (B) Immunoblot, using anti-His antibody, of whole-cell proteins of HMS174(DE3)pLysS transformed with the same plasmids as in panel A.
