For a pyoverdin isolated fromPseudomonas putida it could be shown that Lys is incorpo- rated into the peptide chain by itsε-amine group in contrast to the normally observed con- nection by theα-amino group. The structure elucidation of the pyoverdin by chemical degra- dation and spectroscopic methods is reported and the criteria for the distinction betweenα- andε-connection in the case of Lys are discussed.
