海洋环境中生物可获得的必需微量金属含量极低,这表明海洋生物已经形成了独特的获取、螯合和利用机制。[1]对于海洋无脊椎动物,对这些机制知之甚少,有人认为次级代谢物可能起着至关重要的作用。[2]许多海洋次级代谢产物含有能够络合金属的官能团,但缺乏证据表明这是否发生在体内。[3]海鞘是已知的集中高水平的过渡金属,但这背后的原因并不完全清楚。[4,5]在海鞘血细胞中发现钒的水平非常高,[6]并且已经提出了酪氨酸衍生的被铬三肽的参与[4],尽管最近的证据表明富含半胱氨酸的肽钒素可能是导致Asidia sydneiensis中钒的螯合的原因。[7]然而,缺乏令人信服的证据表明这些金属如何在海洋生物中存在。
The extremely low level of biologically accessible essential trace metals in the marine environment suggests that marine organisms have developed unique mechanisms for their acquisition, sequestration, and utilization.[1] For marine invertebrates, little is known about these mechanisms, and it has been suggested that secondary metabolites may play a vital role.[2] Many marine secondary metabolites contain functional groups that can complex metals, but there is a lack of evidence whether this occurs in vivo.[3] Ascidians are known to concentrate high levels of transition metals, but the reason behind this is not fully understood.[4, 5] Vanadium has been found at highly elevated levels in ascidian blood cells,[6] and involvement of the tyrosine-derived tunichrome tripeptides has been proposed,[4] although more recent evidence indicates that the cysteine-rich peptide vanabins might be responsible for the sequestration of vanadium in Ascidia sydneiensis.[7] There is, however, a lack of convincing evidence to show how these metals occur in marine organisms.
