flai
FlaI is an ATPase protein that forms part of the archaeal flagellum, or archaellum, assembly system. It is an essential cytoplasmic component that uses energy from ATP hydrolysis to power the assembly of the archaellum filament and, in some models, to drive motor activity. FlaI belongs to the AAA+ family of ATPases and shows sequence similarity to bacterial PilB-like motors that power type IV pili, reflecting a conserved mechanism for assembling surface structures in prokaryotes.
In many archaea, FlaI functions as a hexameric motor that coordinates with other components of the archaellum
Genetically, the flaI gene is typically located within the archaeal archaellum gene cluster, alongside other fla
Overall, FlaI is a key component of the archaeal motility apparatus, central to assembling and possibly powering
