Clan: Rubredoxin (CL0045)

Summary

Rubredoxin-like Add an annotation

The Rubredoxin clan is comprised of three families:Rubredoxin, COX5B and desulforedoxin.Rubredoxin domains are small domains (5-6 kDa) and bind one iron atom tetrahedrally bound by four cysteine residues.Similar, desulforedoxin domains are small (4 kDa), but usually form homodimers. Each monomer binds one iron atom, but in a distorted tetrahedral arrangement. COX5B domains are membrane-anchored rubredoxin-like domains. The domain in the Rubredoxin clan are usually comprised of 2 alpha helixes and 2-3 beta strands.

This clan contains 4 families and the total number of domains in the clan is 4680. The clan was built by RD Finn.

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.
