The globally widespread genus Sulfurimonas: versatile energy metabolisms and adaptations to redox clines.

Han Y, Perner M - Front Microbiol (2015)

Bottom Line: Multiple copies of one type of enzyme (e.g., sulfide:quinone reductases and hydrogenases) may play a pivotal role in Sulfurimonas' flexibility to colonize disparate environments.Many of these genes appear to have been acquired through horizontal gene transfer which has promoted adaptations to the distinct habitats.Here we summarize Sulfurimonas' versatile energy metabolisms and link their physiological properties to their global distribution.

ABSTRACT
Sulfurimonas species are commonly isolated from sulfidic habitats and numerous 16S rRNA sequences related to Sulfurimonas species have been identified in chemically distinct environments, such as hydrothermal deep-sea vents, marine sediments, the ocean's water column, and terrestrial habitats. In some of these habitats, Sulfurimonas have been demonstrated to play an important role in chemoautotrophic processes. Sulfurimonas species can grow with a variety of electron donors and acceptors, which may contribute to their widespread distribution. Multiple copies of one type of enzyme (e.g., sulfide:quinone reductases and hydrogenases) may play a pivotal role in Sulfurimonas' flexibility to colonize disparate environments. Many of these genes appear to have been acquired through horizontal gene transfer which has promoted adaptations to the distinct habitats. Here we summarize Sulfurimonas' versatile energy metabolisms and link their physiological properties to their global distribution.

Phylogenetic relationships of NapA sequences to those from Sulfurimonas species. The phylogenetic tree was constructed with the same method as described in Figure 2. The percentage of bootstrap resamplings ≥70 is indicated on the branches. The scale bar represents the expected number of changes per amino acids position. Isolation sources of Sulfurimonas species are indicated in different colors: blue, marine non-vent water system; purple, marine sediments; red, hydrothermal environments.

Mentions: All so far isolated and tested Sulfurimonas species have the periplasmic nitrate reductase (Nap) catalytic subunit (NapA) (Figure 4) and all so far genome sequenced Sulfurimonas species have the napAGHBFLD operon (Sievert et al., 2008b; Sikorski et al., 2010b; Grote et al., 2012; Cai et al., 2014). This organization of the nap operon is distinct from other proteobacterial nap operons (Potter et al., 2001), but is conserved in deep-sea hydrothermal vent Epsilonproteobacteria (Vetriani et al., 2014). Since such vent NapAs have a high affinity for nitrate, they may represent the adaption of Sulfurimonas species to the low nitrate concentrations in vent systems (Vetriani et al., 2014) and other nitrate low environments.
