• Membrane Proteins of Known Structure (from Max Planck Institute in Frankfurt, Germany) not updated since 2006 but useful for tabulation of crystallization conditions.
• Orientations of Proteins in Membranes (OPM) database (University of Michigan, USA) features calculated membrane boundaries for all membrane proteins in the PDB.
• MemProtMD - A database of membrane proteins embedded in lipid bilayers features a database of over 5000 intrinsic membrane protein structures identified in the Protein Data Bank, inserted into simulated lipid bilayers using Coarse-Grained Self Assembly Molecular Dynamics simulations. A few of the MemProtMD workflows have been put together as a set of Google Colab notebooks for establishing membrane protein structures in bilayers, see here.
• The PSIPRED Protein Structure Prediction Server has a highly accurate method for protein secondary structure prediction for proteins without an empirically-determined 3D structure and features also a widely used transmembrane topology prediction method where the output includes a Kyte-Doolittle Hydropathy Plot.
