ASSEMBLY OF THE PEPTIDE CHAINS OF HEMOGLOBIN

Abstract
It is concluded that the growth of the peptide chains of hemoglobin is not a random process but a steady sequential addition of amino acids to growing chains at the rate of approxiamtely 2 amino acids per second. The number of initiation points per chain is at most, very small and most likely only one. The chain growth terminates near or at the free carboxyl end. Taken together, these conclusions indicate that chain growth proceeds steadily from the free amino end toward the free carboxyl end in rabbit hemoglobin.
