Flagellar biosynthesis protein, FliO (IPR022781)

Short name: Flagellar_biosynth_FliO

Overlapping homologous superfamilies


Family relationships



FliO is an essential component of the flagellum-specific protein export apparatus [PMID: 10049367]. It is an integral membrane protein. Its precise molecular function is unknown. FliO is a short protein found in flagellar biosynthesis operons, and which contains a highly hydrophobic N-terminal sequence followed generally by two basic amino acids. This region is reminiscent of but distinct from the twin-arginine translocation signal sequence. Some instances of this gene have been names "FliZ" but phylogenetic tree building supports a single FliO family.
