Flagellar protein FliS (IPR003713)

Short name: FliS

Family relationships

None.

Description

The fliD operon of several bacteria consists of three flagellar genes, fliD, fliS, and fliT, and is transcribed in this order [PMID: 8550529]. In Bacillus subtilis the operon encoding the flagellar proteins FliD, FliS, and FliT is sigma D-dependent [PMID: 8195064].

FliS is a flagellin-specific T3S chaperone that binds in 1:1 stoichiometry to the C-terminal region of flagellin and facilitates its export, preventing polymerization in the cytoplasm [PMID: 11327763, PMID: 12620624, PMID: 16806204]. The fliS gene is necessary for flagellation. In Aeromonas, deletion of this gene (called flaJ) resulted in the complete loss of motility, flagellin expression, and adherence [PMID: 11401962].
