Protein translocation across cellular membranes is an essential and nano-scale dynamic process. Here, the authors visualize protein translocation via the SecYEG-SecA complex in a nanodisc by high-speed atomic force microscopy (HS-AFM), shedding light on the structural changes of SecA in this process.
