A pyoverdine from Pseudomonas putida CFML 90-51 with a Lys ε-amino link in the peptide chain

From Pseudomonas putida CFML 90-51--a hospital isolate--a pyoverdine was obtained which is characterized by the unusual linkage by the epsilon--rather than the alpha-amino group of Lys in the peptide chain. The structure elucidation by spectroscopic methods and degradation reactions is reported.
