Claim 0:
1. A method for the modification of all or part of the polypeptide content of a substrate comprising peptides, polypeptides and/or proteins harbouring a N-terminus glycine residue, comprising contacting all or part of the substrate, peptides, polypeptides and/or proteins harbouring a N-terminus glycine residue, with at least a TET protein harbouring at least a N-terminus glycine residues specific exopeptidase activity, said at least TET protein comprising the amino acid sequence as set forth in SEQ ID NO: 1, or with any homologous protein derived from said at least TET protein as set forth in SEQ ID NO: 1 by substitution, addition or deletion of at least one amino acid, provided that the derived protein retains at least 79% of identity with the amino acid sequence as set forth in SEQ ID NO: 1, and said derived protein retaining a N-terminus glycine residues specific exopeptidase activity.
