What is MemBlob?

MemBlob implements the first algorithm ever to determine the membrane boundaries of transmembrane proteins based on a larger set of experimental data, namely electron densities. The membrane environment used for structure determination cannot be resolved at the atomic level, but it produces electron density, which can be utilized to dissect the membrane embedded part of the protein.

DATABASE:

We ran our pipline on structures determined by cryo-EM at a resolution better than 4 Å. Structures, corresponding electron density maps, and TMDET XML files were downloaded from RCSB, EMD, and TMDET respectively (July, 2018).
