Abstract

Paenirhodobacter enshiensis is a non-photosynthetic species that belongs to family Rhodobacteraceae. Here we report the draft genome sequence of Paenirhodobacter enshiensis DW2-9T and comparison results to the available related genomes. The strain has a 3.4 Mbp genome sequence with G + C content of 66.82 % and 2781 protein-coding genes. It lacks photosynthetic gene clusters and putative proteins necessary in Embden-Meyerhof-Parnas (EMP) pathway, but contains proteins in Entner-Doudoroff (ED) pathway instead. It shares 699 common genes with nine related Rhodobacteraceae genomes, and possesses 315 specific genes.Electronic supplementary materialThe online version of this article (doi:10.1186/s40793-015-0026-9) contains supplementary material, which is available to authorized users.

Highlights

Family Rhodobacteraceae belongs to Proteobacteria which was established by Garrity et al [1] and contains 105 genera including both chemoorganotrophic and photoheterotrophic bacteria
We report the genomic features of P. enshiensis DW2-9T and the comparison results to the close relatives
The 16S rRNA gene based phylogenetic tree showing the phylogenetic relationships of P. enshiensis DW2-9T to other taxonomically classified type strains of the family Rhodobacteraceae could be found in our previous study [9]

Summary

Introduction

Rhodobacteraceae belongs to Proteobacteria which was established by Garrity et al [1] and contains 105 genera including both chemoorganotrophic and photoheterotrophic bacteria. In order to provide genomic information for elucidating the mechanism of bacterial selenite reduction, as well as the taxonomic study, we performed genome sequencing of strain P. enshiensis DW2-9T, together with its close relatives Haematobacter missouriensis CCUG 52307T [10] and Haematobacter massiliensis CCUG 47968T [11]. The 16S rRNA gene based phylogenetic tree showing the phylogenetic relationships of P. enshiensis DW2-9T to other taxonomically classified type strains of the family Rhodobacteraceae could be found in our previous study [9].
