Please provide a membrane protein in PDB file format. Note: Since ProBLM uses membrane protein specific geometries and properties, the uploaded protein should be a membrane protein (homology models are acceptable). The uploaded protein file will also be subjected to a 'fixing' algorithm where missing residues and/or heavy atoms will be added. If you choose to upload your own membrane file, it should also be in PDB format. The user supplied membrane file can have waters, be of any dimensions, and contain any lipid structure.
