Consistent with prior observations, typhoid toxin made by wild-type Typhi caused cell distension and cell-cycle arrest in G2/M within a toxin dose-dependent way (Statistics 3AC3C), whose specificity was verified using an isogenic mutant Typhi-producing typhoid toxin carrying the catalytic-mutant CdtBH160Q subunit (STy CdtB mt) whose cell-cycle arrest profiles in G2/M was comparable with this of […]
