A siderophore, named bisucaberin B, was isolated from Tenacibaculum mesophilum bacteria separated from a marine sponge collected in the Republic of Palau. Using spectroscopic and chemical methods, the structure of bisucaberin B (1) was clearly determined to be a linear dimeric hydroxamate class siderophore. Although compound 1 is an open form of the known macrocyclic dimer bisucaberin (2), and was previously described as a bacterial degradation product of desferrioxamine B (4), the present report is the first description of the de novo biosynthesis of 1. To the best of our knowledge, compound 1 is the first chemically characterized siderophore isolated from a bacterium belonging to the phylum Bacteroidetes.
从帕劳共和国采集的海洋海绵中分离出的嗜中性天牛细菌(Tenacibaculum mesophilum)中分离出了一种苷元,命名为双琥珀苷 B。通过光谱和化学方法,明确确定了双琥珀酰 B(1)的结构,它是一种线性二聚羟酰胺类苷酸盐。尽管化合物 1 是已知大环二聚体双葫芦巴苷(2)的开放形式,而且以前曾被描述为去铁胺 B 的细菌降解产物(4),但本报告首次描述了 1 的全新生物合成过程。据我们所知,化合物 1 是第一个从属于类杆菌门的细菌中分离出来的具有化学特征的苷元。
