title: C-terminal sequence analysis.
abstract: Carboxy-terminal (C-terminal) sequence analysis is used for direct confirmation of the C-terminal sequence of native and expressed proteins, for detection and characterization of protein processing at the C-terminus, for identification of post-translational proteolytic cleavages, and for obtaining partial sequence information on N-terminally blocked protein samples in order to facilitate design of oligonucleotide probes for gene cloning. This unit describes an automated chemical method and a manual enzymatic (carboxypeptidase digestion) method for determining C-terminal sequence information. Carboxypeptidase digestion requires only a standard amino acid analysis method.
