Protein
Polar flagellar hook-associated protein 2
Organism
Vibrio parahaemolyticus serotype O3:K6 (strain RIMD 2210633)
Function
Required for the morphogenesis and for the elongation of the flagellar filament by facilitating polymerization of the flagellin monomers at the tip of growing filament. Forms a capping structure, which prevents flagellin subunits (transported through the central channel of the flagellum) from leaking out without polymerization at the distal end. Important for swimming motility.
Similarity
Belongs to the FliD family.
