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.

Clan: beta_Roll (CL0592)

Summary

beta-strand roll of R-module, superfamily Add an annotation

This superfamily is characterised by families of a short nonarepeat unit. The beta-roll is made up of a super-helix of beta-strand-turns of two short strands each, and the loops are stabilised by Ca2+ ions. The region of a protein with this beta-roll is often termed the R-module, and it can frequently be found in metalloproteases of the serralysin type and in epimerases [1]. The nonarepeat is also found multiple times in haemolysins, where the structure is again stabilised by binding Ca2+ ions.

This clan contains 2 families and the total number of domains in the clan is 129323. The clan was built by 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.
