Summary

Cupin fold Add an annotation

This clan represents the conserved barrel domain of the 'cupin' superfamily [1] ('cupa' is the Latin term for a small barrel). The cupin fold is found in a wide variety of enzymes, but notably contains the non-enzymatic seed storage proteins also.

This clan contains 65 families and the total number of domains in the clan is 361513. 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.
