Flagellin, archaea (IPR002774)

Short name: Flagellin_arc

Overlapping homologous superfamilies


Family relationships



Archaeal motility occurs by the rotation of flagella that are different to bacterial flagella, but show similarity to bacterial type IV pili. These similarities include the multiflagellin nature of the flagellar filament, N-terminal sequence similarities, as well as the presence of homologous proteins in the two systems [PMID: 16983194, PMID: 11250034]. Also unlike bacterial flagellins but similar to type IV pilins, archaeal flagellins are initially synthesised with a short leader peptide that is cleaved by a membrane-located peptidase [PMID: 11250034, PMID: 15170402]. The enzyme responsible for the removal of the this leader peptide is FlaK [PMID: 14622420].
