Summary
AIG2/ChaC-like superfamily
The structure consists of a five-stranded beta-barrel surrounded by two alpha-helices and a small beta-sheet. Conservation of residues in a hydrophilic cavity able to bind small ligands in some members suggests that this may also serve as an active site.
This clan contains 3 families and the total number of domains in the clan is 13516. 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.
