Abstract
An open reading frame of 74 codons was identified downstream of the nifB gene of Bradyrhizobium japonicum 110. The predicted amino acid sequence shared 63% similarity with the Rhodopseudomonas palustris ferredoxin I sequence. We propose to name the gene frxA. The frxA gene was found to be cotranscribed with the nifB gene. An insertion mutation within frxA hardly affected nitrogen fixation activity.
摘要
在日本慢生根瘤菌110的nifB基因下游鉴定出一个由74个密码子组成的开放阅读框。预测的氨基酸序列与沼泽红假单胞菌铁氧化还原蛋白I序列有63%的相似性。我们提议将该基因命名为frxA。发现frxA基因与nifB基因共转录。frxA内的插入突变几乎不影响固氮活性。
