This interaction is crucial for mobilizing the molecular motor kinesin-1 on the bacterial vacuole, and key structural motifs, including the WXXXE motif, are shown to be essential for SifA’s stability and proper translocation."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nThe second abstract further dissects SifA’s functional architecture, revealing that its two distinct domains contribute to virulence.
