EncoMPASS

The Encyclopedia of Membrane Proteins Analyzed by Structure and Symmetry (EncoMPASS) is an automated database for relating integral membrane proteins of known structure from the points of view of their sequence, structure, and quaternary and internal symmetries. Analysis is presented for all membrane-spanning PDB entries, and separately for all membrane-spanning chains found therein. Only X-ray crystallographic structures with resolution ≤3.5Å are included.
