Please note: when we start each new Pfam data release, we take a copy of the UniProt sequence database. This snapshot of UniProt forms the basis of the overview that you see here. It is important to note that, although some UniProt entries may be removed after a Pfam release, these entries will not be removed from Pfam until the next Pfam data release.

Sequence information

This is the amino acid sequence of the UniProt sequence database entry with the accession P0A6X7. This sequence is stored in the Pfam database and updated with each new Pfam release, but this means that the sequence we store may differ from that stored by UniProt.

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe SIFTS project, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between Pfam domains, this UniProt entry and a corresponding three dimensional structure.
