Protein Family Models

Flagellins polymerise to form bacterial flagella. This family includes flagellins and hook associated protein 3. Structurally this family forms an extended helix that interacts with Pfam:PF00700. [1]. 7648320. Spinning tails. DeRosier DJ;. Curr Opin Struct Biol 1995;5:187-193. (from Pfam)

flagellar hook-associated protein FlgL, together with FlgK, forms the junction between the hook and the filament in the flagellum and provides a structural base where flagellin, a filament-forming protein, is inserted for the initiation of filament elongation; similar to Escherichia coli FlgL (also known as HAP3)

This protein family consists of flagellar hook-associated proteins designated FlgL (or HAP3) encoded in bacterial flagellar operons. A N-terminal region of about 150 residues and a C-terminal region of about 85 residues are conserved. Members show considerable length heterogeneity between these two well-conserved terminal regions; the seed alignment 486 columns, 393 of which are modeled in the HMM, while members of this family are from 287 to over 500 residues in length. This model distinguishes FlgL from the flagellin gene product FliC.
