硫活化（SUF）系统是参与铁硫簇生物合成和维持的三大系统之一。在真核生物中，SUF系统是质体特异性的，因此是共生起源的。在隐芽植物的分析表明，一个独特的遗传划分的SUF系统，至少有两个不同的基因转移事件演变。我们分析了一个组件，SufD，在隐藻吉拉尔迪亚theta和拟南芥。我们证明了SufD在A. thaliana. (C)2005年欧洲生物化学学会联合会。Elsevier B.V.出版，保留所有权利。
The mobilization of sulfur (SUF) system is one of three systems involved in iron-sulfur cluster biosynthesis and maintenance. In eukaryotes the SUF system is specific for the plastid and therefore of symbiotic origin. Analyses in cryptophytes showed a unique genetic compartmentalization of the SUF system, which evolved by at least two different gene transfer events. We analyzed one of the components, SufD, in the cryptophyte Guillardia theta and in Arabidopsis thaliana. We demonstrated that SufD fulfils house keeping functions during embryogenesis and in adult plants in A. thaliana. (C) 2005 Federation of European Biochemical Societies. Published by Elsevier B.V.
