§ An on-line, searchable, relational database with select structural and functional information on membrane proteins and peptides
§ 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
§ Updated weekly in parallel with the Protein Data Bank
