Identification of AI-2 Quorum Sensing Inhibitors in Vibrio harveyi Through Structure-Based Virtual Screening
Quorum sensing (QS) is a cell-to-cell communication system that regulates gene expression as a result of the production and perception of signal molecules called autoinducers (AIs). AI-2 is a QS autoinducer pr...

Analysis of Yops Secretion by Yersinia pestis Type III Secretion System
The type III secretion system (T3SS) is a highly conserved virulence mechanism that is widely distributed in Gram-negative bacteria. Three pathogenic Yersinia species share a common T3SS encoded by a 70-kb plasmi...
