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.
鸟分枝杆菌分泌一种名为外螯合铁载体的铁结合铁载体。此前有报道称,鸟分枝杆菌的外螯合铁载体具有以羧酸结尾的不饱和侧链。相比之下,我们的数据显示侧链既有饱和的也有不饱和的,且以羧酸盐或甲酯结尾。
