A model is proposed of the polypeptide chain in bovine pancreatic ribonuclease based on a 2 A electron density map involving 7,294 reflexions and data from seven heavy atom derivatives. The molecule seems to be roughly kidney shaped with dimensions of about 38 × 28 × 22 A with a deep depression in the middle of one side. The model disagrees with that based on a 5.5 A map suggested by Dr. C. H. Carlisle et al. (Nature, 213, 557; 1967).
