Shotgun proteomic data of Desulfosarcina variabilis 3be13

ABSTRACT: Sulfate-reducing bacteria (SRB) play a pivotal role in the global carbon- and sulfur cycles, especially in the marine environment. Here, continental margins, coastal ranges, and shelf sediments stand out by their high input of organic matter, and more than 50% of their mineralization is achieved in the upper sediment layers, coupled to sulfate reduction. This turnover is mainly achieved by members of the family of Desulfobacteraceae of completely oxidizing SRB. Desulfosarcina variabilis 3be13 is a member of this family.

Marine sediments are highly bioactive habitats, where sulfate-reducing bacteria contribute substantially to seabed carbon cycling by oxidizing ~77 Tmol C<sub>org</sub> year<sup>-1</sup>. This remarkable activity is largely attributable to the deltaproteobacterial family <i>Desulfobacteraceae</i> of complete oxidizers (to CO<sub>2</sub>), which our biogeography focused meta-analysis verified as cosmopolitan. However, the catabolic/regulatory networks underlying this ecophysiological feat at the t  ...[more]
