摘要

假单胞菌属菌株DNDY-54是一种反硝化细菌，从印度洋九十东脊的深海沉积物样本中分离得到。在这里，我们发现DNDY-54的全基因组有一条圆形染色体，长度为4,412,895 bp，平均GC含量为60.57%。全基因组包含4111个预测蛋白编码基因，59个trna和4个rRNA操纵子，为16S-23S-5S rRNA。在注释结果的基础上，我们确定了编码27种与氮代谢相关的蛋白质的基因，包括构成完整反硝化途径的酶。这项工作将提高对深层生物圈氮循环的认识，并为环境保护和废水处理提供新的候选物。

Complete genome sequence of the denitrifying Pseudomonas sp. strain DNDY-54 isolated from deep-sea sediment of ninety east ridge

Pseudomonas sp. strain DNDY-54, a denitrifying bacterium, was isolated from a deep-sea sediment sample from Ninety East Ridge in the Indian Ocean. Here, we show that the complete genome of DNDY-54 has one circular chromosome of 4,412,895 bp with mean 60.57% GC content. The complete genome contains 4111 predicted protein-coding genes, 59 tRNAs, and 4 rRNA operons as 16S–23S-5S rRNA. On the basis of the annotation results, we identified genes that encode 27 proteins related to nitrogen metabolism, including enzymes that make up a complete denitrifying pathway. This work will improve the understanding of nitrogen cycling in the deep biosphere and provides a new candidate for protection of the environment and applications in waste water disposal.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
