1.A.104.1.1
The FlhA flagellar biosyththesis energizer Na+ channel of 692 aas and 8 TMSs.  Evidence for the Na+ channel activity of FlhA has been presented (Minamino et al. 2016). FlhA and FlhB are transmembrane proteins of the flagellar type III protein export apparatus (TC# 3.A.6), and their C-terminal cytoplasmic domains (FlhAC and FlhBC) coordinate flagellar protein export with assembly. Their  (Minamino et al. 2020). FliK-driven conformational rearrangements of FlhA and FlhB are required for export switching of the flagellar protein export apparatus (Minamino et al. 2020).
