Abstract |
Type III secretion systems (T3SS) are highly conserved virulence factors employed by a large number of pathogenic gram-negative bacteria. Like many T3SS translocators, recombinant expression of the hydrophobic Shigella protein IpaB requires the presence of its cognate chaperone IpgC. Chaperone-bound IpaB is maintained in a nonfunctional state, which has hampered in vitro studies aimed at understanding molecular structure and function of this important class of T3SS proteins. Herein, we describe an expression and purification protocol that utilizes mild detergents to produce highly purified, homogeneous IpaB of defined oligomeric states. |
