Characterization of exochelins of Mycobacterium avium: evidence for saturated and unsaturated and for acid and ester forms.
Mycobacterium avium secretes iron-binding siderophores called exochelins. The exochelins from M. avium have previously been reported to have unsaturated side chains that terminate in carboxylic acid. In contrast, our data show the side chains to be both saturated and unsaturated and to terminate with either a carboxylate or methyl ester.
