Two studies on mycoplasma pneumoniae show with cryo-electron tomography how transcription, protein synthesis, membrane transport and folding are spatially coupled. The 3D images make both long suspected supercomplexes and a previously unknown folding machine visible on the cell surface. Heidelberg (Germany). Ribosomes, RNA polymerases and membrane transporters are often examined individually in structural biology. However, in intact cells such m…
