Pirellula sp.菌株1（“Rhodopirellula baltica”）是全球分布的和对环境重要的浮游菌目细菌的海洋代表。在这里，我们报告的完整基因组序列的成员，这一独立的门。Pirellula sp.菌株1具有7.145兆碱基，是迄今为止测序的最大的环状细菌基因组。异乳酸发酵所需的所有基因的存在下，C1化合物的相互转化的关键基因，和110硫酸酯酶是意想不到的好氧异养分离。尽管Pirellula sp.菌株1具有蛋白质细胞壁，但仍发现了肽聚糖合成基因的残余。脂质A生物合成基因和鞭毛L-和P-环蛋白的同源物表明细胞壁为前革兰氏阴性类型。所有相关标记的系统发育分析清楚地将浮游菌目作为一个独特的门归属于细菌域，但我们的分析不支持最深的分支。
Pirellula sp. strain 1 ("Rhodopirellula baltica") is a marine representative of the globally distributed and environmentally important bacterial order Planctomycetales. Here we report the complete genome sequence of a member of this independent phylum. With 7.145 megabases, Pirellula sp. strain 1 has the largest circular bacterial genome sequenced so far. The presence of all genes required for heterolactic acid fermentation, key genes for the interconversion of C1 compounds, and 110 sulfatases were unexpected for this aerobic heterotrophic isolate. Although Pirellula sp. strain 1 has a proteinaceous cell wall, remnants of genes for peptidoglycan synthesis were found. Genes for lipid A biosynthesis and homologues to the flagellar L- and P-ring protein indicate a former Gram-negative type of cell wall. Phylogenetic analysis of all relevant markers clearly affiliates the Planctomycetales to the domain Bacteria as a distinct phylum, but a deepest branching is not supported by our analyses.
