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

Coiled-coil helix coiled-coil helix superfamily Add an annotation

The conserved [coiled coil 1]-[helix 1]-[coiled coil 2]-[helix 2] domain (CHCH domain) superfamily members include NADH-ubiquinone oxidoreductases, some cytochrome oxidases and yeast mitochondrial ribosomal proteins. Within each helix of the CHCH domain there are two cysteines present in a C-X9-C motif.

This clan contains 8 families and the total number of domains in the clan is 16008. The clan was built by A Bateman.

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.
