Flagellar hook-associated protein 3 (IPR013384)

Short name: Flagell_FlgL

Overlapping homologous superfamilies


Family relationships



FlgL (or hook-associated protein 3, HAP3) proteins are flagellar hook-associated proteins encoded in bacterial flagellar operons [PMID: 8158647, PMID: 12940991]. An N-terminal region of about 150 residues and a C-terminal region of about 85 residues are conserved in this family, though members show considerable length heterogeneity between these two well-conserved terminal regions - proteins in this family range from 287 to more than 500 residues in length.
