Powering down the Pfam website
On October 5th, we began redirecting traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will remain available at pfam-legacy.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Summary

Type III secretion system types a and b chaperone Add an annotation

Type III secretion systems of the two forms, a - translocation-associated, and b - bacterial flagellum, share homology between comparable parts. This superfamily includes the chaperone proteins FliJ and HrpB7.

This clan contains 4 families and the total number of domains in the clan is 3069. The clan was built by RD Finn and P Coggill.

Structures

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
