(Microbial infection) Probably transports the toxic C-terminal region of CdiA-2 from B.pseudomallei strain 1026b across the inner membrane to the cytoplasm, where CdiA has a toxic effect. Expression in E.coli makes the bacteria sensitive to the tRNase domain of B.pseudomallei strain 1026b CdiA-2. Disruption confers resistance to cellular contact-dependent growth inhibition (CDI) CdiA-2 of B.pseudomallei strain 1026b, but not to endogenous CdiA. Unchanged binding to B.pseudomallei strain 1026b inhibitor cells.
