Abstract
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-accepting chemotaxis protein genes, including four that may
assist in positioning it in the redoxcline. A relative abundance of coding sequences (CDSs) encoding regulatory
proteins likely control the expression of genes encoding carboxysomes, multiple dissolved inorganic nitrogen and
phosphate transporters, as well as a phosphonate operon, which provide this species with a variety of options for
acquiring these substrates from the environment. Thiom. crunogena XCL-2 is unusual among obligate sulfur-oxidizing
bacteria in relying on the Sox system for the oxidation of reduced sulfur compounds. The genome has characteristics
consistent with an obligately chemolithoautotrophic lifestyle, including few transporters predicted to have organic
allocrits, and Calvin-Benson-Bassham cycle CDSs scattered throughout the genome.
