An on-line, searchable, relational database with select structural and functional information on membrane proteins and peptides


Data comes from the Protein Data Bank (PDB) and other databases, and from the literature


Covers integral, anchored and peripheral membrane proteins and peptides 


Structures are based on x-ray diffraction, nuclear magnetic resonance, electron diffraction and cryo-electron microscopy


Searchable on-line by protein characteristic, structure method, crystallization technique, detergent, temperature, pH, author, etc.


Statistical analysis of MPDB records can be performed and viewed on-line


Hot-linked to the PDB and Pfam for viewing sequence, 3-D structure and domain architecture, and for downloading coordinates


Updated weekly in parallel with the Protein Data Bank
