Atomic force microscopy captures folded ribosome bound nascent chains.
Direct visualization of co-translational folding of nascent polypeptide chains is challenging. Here we present, for the first time, AFM images of large protein constructs based on the membrane binding domain of ankyrin-R, complexed with the ribosome. The characteristic "horse-shoe" shape of ankyrin-R emerging from the ribosome was captured.
