摘要
Crassaminicella sp. 143-21是一种隶属于梭菌科(Clostridiaceae)的厌氧、嗜热、杆状细菌，是一种从印度洋中部脊(CIR)深海热液喷口烟囱中分离出来的新种。本研究获得了菌株143-21的全基因组序列，全长2,756,133 bp, G + C含量为31.1%。共获得蛋白编码基因2427个，tRNA基因121个，rRNA基因33个。对菌株143-21的基因组分析显示，菌株143-21中存在大量与有机物转运和分解代谢相关的基因，包括肽转运、氨基酸转运、糖转运、乙醇胺转运以及相应的代谢途径。此外，基因组包含大量参与翻译、核糖体结构和信号转导的基因。这些基因可能有助于深海热液喷口环境中微生物的生存。菌株143-21的基因组将有助于进一步了解其在深海热液喷口环境中的适应策略。
Complete genome sequence of Crassaminicella sp. 143-21，isolated from a deep-sea hydrothermal vent
Crassaminicella sp. 143-21, a putative new species isolated from deep-sea hydrothermal vent chimney on the Central Indian Ridge (CIR), is an anaerobic, thermophilic and rod-shaped bacterium belonging to the family Clostridiaceae. In this study, we present the complete genome sequence of strain 143-21, comprising 2,756,133 bp with a G + C content of 31.1%. In total, 2427 protein coding genes, 121 tRNA genes and 33 rRNA genes were obtained. Genomic analysis of strain 143-21 revealed that numerous genes related to organic matter transport and catabolism, including peptide transport, amino acid transport, saccharide transport, ethanolamine transport and corresponding metabolic pathways. Further, the genome contains a large proportion of genes involved in translation, ribosomal structure, and signal transduction. These genes might facilitate microbial survival in deep-sea hydrothermal vent environment. The genome of strain 143-21 will be helpful for further understanding its adaptive strategies in the deep-sea hydrothermal vent environment.
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.
