Protein Family Models

Members of this protein family are the FliI protein of bacterial flagellum systems. This protein acts to drive protein export for flagellar biosynthesis. The most closely related family is the YscN family of bacterial type III secretion systems. This model represents one (of three) segment of the FliI family tree. These have been modeled separately in order to exclude the type III secretion ATPases more effectively.

flagellar protein export ATPase FliI is the catalytic subunit of a protein translocase for flagellum-specific export, or a proton translocase involved in local circuits at the flagellum

This family of ATPases demonstrates extensive homology with ATP synthase F1, beta subunit. It is a mixture of members with two different protein functions. The first group is exemplified by Salmonella typhimurium FliI protein. It is needed for flagellar assembly, its ATPase activity is required for flagellation, and it may be involved in a specialized protein export pathway that proceeds without signal peptide cleavage. The second group of proteins function in the export of virulence proteins; exemplified by Yersinia sp. YscN protein an ATPase involved in the type III secretory pathway for the antihost Yops proteins.
