摘要：

The structure of azoverdin, the major peptidic siderophore of Azomonas macrocytogenes ATCC 12334, was elucidated using FAB-MS and high field NMR techniques. It is a chromopeptide possessing at its N-terminal end a fluorescent chromophore derived from 2,3-diamino-6,7-dihydroxyquinoline and at its C-terminal end 2,4-diaminobutyric acid in the lactam form (cDab). The other amino acids are: homoserine (2), N(delta)-acetyl,N(delta)-hydroxyornithine (2) and serine (1). The structure of azoverdin is (Succinamide)-Chromophore-(L)-Hse-(D,L)-N(delta)Acetyl,N(delta)OHOrn-(D)-Ser-N(delta)Acetyl,N(delta)OHOrn-(D)-Hse-(L)-cDab.
