I made this diagram for someone a decade ago, whose name (LS) means nothing to me and the names of the protein complexes escape me. It was a cover submission for an article submitted to PNAS at some point and didn’t make the cut, and I am sure LS never paid me.  It has some interesting information in it anyway so I am posting it as an illustration.  This version is considerably modified so I am not breaking any copyrights…besides it was my illustration in the first place (LOL).
