The carbon-concentrating mechanism of the hydrothermal vent chemolithoautotroph Thiomicrospira crunogena.
Chemolithoautotrophic bacteria grow in habitats with a variety of dissolved inorganic carbon (DIC) concentrations and are likely to have transport-related adaptations to DIC scarcity. Carbon-concentrating mechanisms (CCMs) are present in many species of cyanobacteria, enabling them to grow in the presence of low concentrations of CO2 by utilizing bicarbonate transporters and CO2 traps to genera...
متن کاملThe Genome of Deep-Sea Vent Chemolithoautotroph Thiomicrospira crunogena XCL-2
Presented here is the complete genome sequence of Thiomicrospira crunogena XCL-2, representative of ubiquitous chemolithoautotrophic sulfur-oxidizing bacteria isolated from deep-sea hydrothermal vents. This gammaproteobacterium has a single chromosome (2,427,734 base pairs), and its genome illustrates many of the adaptations that have enabled it to thrive at vents globally. It has 14 methyl-acc...
متن کاملExpression and function of four carbonic anhydrase homologs in the deep-sea chemolithoautotroph Thiomicrospira crunogena.
The hydrothermal vent chemolithoautotroph Thiomicrospira crunogena grows rapidly in the presence of low concentrations of dissolved inorganic carbon (DIC) (= CO(2) + HCO(3)(-) + CO(3)(-2)). Its genome encodes alpha-carbonic anhydrase (alpha-CA), beta-CA, carboxysomal beta-like CA (CsoSCA), and a protein distantly related to gamma-CA. The purposes of this work were to characterize the gene produ...
متن کاملMetagenomic Comparison of Two Thiomicrospira Lineages Inhabiting Contrasting Deep-Sea Hydrothermal Environments
BACKGROUND The most widespread bacteria in oxic zones of carbonate chimneys at the serpentinite-hosted Lost City hydrothermal field, Mid-Atlantic Ridge, belong to the Thiomicrospira group of sulfur-oxidizing chemolithoautotrophs. It is unclear why Thiomicrospira-like organisms thrive in these chimneys considering that Lost City hydrothermal fluids are notably lacking in hydrogen sulfide and car...
