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

IHF-like DNA-binding protein superfamily Add an annotation

This superfamily is characterised by being a dimer of identical subunits of a core of four helices in a bundle, partly opened, capped with a beta-sheet. All members appear to be prokaryotic DNA-binding domains.

This clan contains 8 families and the total number of domains in the clan is 23984. The clan was built by P Coggill.

Members

This clan contains the following 8 member families:

Bac_DNA_binding HU-CCDC81_bac_1 HU-CCDC81_bac_2 HU-CCDC81_euk_1 HU-CCDC81_euk_2 HU-DNA_bdg HU-HIG Tra_M

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.
