The （His）6 fusion protein was identified by SDS-PAGE and Western blot. The recombinant protein was purified by affinity chromatography, and the calculated molecular mass（Mr） was 88000. The results of the sequence analysis indicate that the cloned gene（GeneBank accession No. EU124675） was a supplement and revision of the reported ACCase CT partial cDNA from Chinese Spring wheat plastid. The recombinant protein will be significant for us to investigate the recognizing mechanism between ACCase and herbicides, and further to screen new herbicides.展开更多
乙酰CoA羧化酶(acetyl CoA carboxylase,ACC)是脂肪酸合成的限速酶,它催化乙酰CoA合成丙二酰CoA,对 脂肪的合成起着重要的调节作用,它与肥胖的发生及发展关系密切。ACC在体内受多种激素的调节,运动及饮食也 能通过调节ACC的活性来调节...乙酰CoA羧化酶(acetyl CoA carboxylase,ACC)是脂肪酸合成的限速酶,它催化乙酰CoA合成丙二酰CoA,对 脂肪的合成起着重要的调节作用,它与肥胖的发生及发展关系密切。ACC在体内受多种激素的调节,运动及饮食也 能通过调节ACC的活性来调节体内脂代谢过程。展开更多
