• • N-Terminal Sequencing: Approaches for Confirming Mature Protein Starts and Processing Sites

  Many proteins do not begin with the first residue encoded in the gene. Signal peptides are removed during secretion. Propeptides may be cleaved before the mature form becomes active. Recombinant expression systems can leave unintended N-terminal extensions or fail to remove leader sequences as expected. In each case, the biologically relevant question is not only what the gene encodes, but where the mature protein actually starts.
