Abstract

The possibility of sequencing peptides or proteins from their N-terminal ends became a reality with the discovery and the application of the Edman stepwise degradation (1,2; also see Chapter 36). The procedure developed was automated in 1967 (2), and it is now possible to obtain unequivocal sequence information for up to 35–70 residues for a wide variety of peptides and proteins before the buildup of background material makes assignments difficult, if not impossible. In practice, the complete sequence often has to be derived by establishing the sequences of smaller fragments (i.e., peptides) obtained from the peptide by the action of either enzymes or chemical reagents (3).
