The ribosome produces most proteins. Here we report high-performance chemistry matched with an automated flow instrument for the direct manufacturing of peptide chains up to 164 amino acids over 328 consecutive reactions. The machine is rapid; chain elongation is complete in hours. We demonstrated this approach's utility by synthesizing different protein chains that represent enzymes, structural units, and interaction hubs. After purification and folding, the synthetic material had biophysical and enzymatic properties comparable to the biologically produced proteins. High-fidelity automated flow chemistry is an alternative to manufacturing single-domain proteins without the ribosome.
