线粒体DNA编码蛋白质亚基的研究
The Research Progress of Protein Subunits Coded by The Mitochondrial DNA
【摘要】 人类线粒体DNA(mtDNA)是全长为16569 bp的双链闭环分子,除负责编码2种rRNA和22种tRNA外,还参与了4种呼吸酶复合物(13种多肽)的形成。包括NADH-CoQ还原酶(NADH-CoQ reductase,ND)中的7个亚基(ND1-6,4L);泛醌-细胞色素C还原酶(CoQ-Cytc reductase)的1个亚基(Cyt-b);细胞色素C氧化酶(cytochrome Coxidase,COX)中的3个亚基(COX I-III);ATP合成酶(ATPase)中的2个亚基(ATPase6,8)。本文就人线粒体DNA编码的各蛋白亚基的结构、功能和研究进展进行综述。
【Abstract】 The total length of the human mitochondrial DNA(double loop molecular chain)was 16,569 bp,the genome content of human including 2 rRNA,22 tRNA,and 13 protein-coding genes.The 13 protein-coding genes were NADH dehydrogenase subunits 1-6 and 4L genes;cytochrome c oxidase subunits I-III genes;cytochrome b gene;ATPase subunits 6 and 8 genes;In the present review,the composition,the structure and function,the most significant studies on the 13 protein-coding genes are reported.
