Abstract

The genus is a predominant member of host-associated microbiome. We here report on the genomic analysis of strain Russ that was isolated from a trashcan at Oklahoma State University, Stillwater, OK. The draft genome of strain Russ consists of 3,939,877 bp of DNA with 3704 protein-coding genes and 134 RNA genes. This is the first report of a genome sequence of a member of . Genomic analysis revealed metabolic versatility with genes involved in the metabolism and transport of all amino acids as well as glucose, fructose, mannose, xylose, arabinose and galactose, suggesting the organism is a versatile heterotroph. The genome also encodes an extensive secretory machinery including types I, II, III, IV, and Vb secretion systems, and several genes for pili production including the new usher/chaperone system (pfam 05,229). The implications of these systems for opportunistic pathogenesis are discussed.

摘要

该属是宿主相关微生物群的主要成员。我们在此报告从俄克拉荷马州立大学斯蒂尔沃特分校的一个垃圾桶中分离出的Russ菌株的基因组分析。Russ菌株的基因组草图由3,939,877 bp的DNA组成,有3704个蛋白质编码基因和134个RNA基因。这是关于该属成员基因组序列的首次报告。基因组分析揭示了其代谢多样性,具有参与所有氨基酸以及葡萄糖、果糖、甘露糖、木糖、阿拉伯糖和半乳糖代谢与转运的基因,表明该生物体是一种多功能异养生物。该基因组还编码广泛的分泌机制,包括I型、II型、III型、IV型和Vb型分泌系统,以及几个用于菌毛产生的基因,包括新的组装分子伴侣系统(pfam 05,229)。讨论了这些系统在机会性致病方面的意义。
