The sdhCDAB operon, encoding succinate dehydrogenase, was cloned from the soybean symbiont Bradyrhizobium japonicum. Sdh from B. japonicum is phylogenetically related to Sdh from mitochondria. This is the first example of a mitochondrion-like Sdh functionally expressed in Escherichia coli.
编码琥珀酸脱氢酶的sdhCDAB操纵子是从大豆共生菌慢生根瘤菌中克隆出来的。慢生根瘤菌中的琥珀酸脱氢酶(Sdh)在系统发育上与线粒体中的Sdh相关。这是在大肠杆菌中功能性表达的线粒体样Sdh的首个实例。
