The DNA sequences encoding component C of methyl coenzyme M reductase (mcr genes) in Methanothermus fervidus, Methanobacterium thermoautotrophicum, Methanococcus vannielii, and Methanosarcina barkeri have been published. Comparisons of transcription initiation and termination sites and of the amino acid sequences of the mcr gene products are presented. Structural features conserved within the amino acid sequences are identified and a comparison of methyl reductase with other disulfide bond synthesizing enzymes is presented.
嗜热甲烷栖热菌、嗜热自养甲烷杆菌、瓦氏甲烷球菌和巴氏甲烷八叠球菌中编码甲基辅酶M还原酶C组分的DNA序列(mcr基因)已发表。文中给出了mcr基因转录起始和终止位点以及mcr基因产物氨基酸序列的比较结果。鉴定了氨基酸序列中保守的结构特征,并将甲基还原酶与其他二硫键合成酶进行了比较。
