Abstract
The characterization of transcriptional start sites of 14 genes encoded by the extremely AT-rich genome of "Candidatus Blochmannia floridanus" revealed a high degree of conservation with the RpoD promoter consensus sequence of the free-living relative Escherichia coli. Moreover, in agreement with the presence of the alternative heat shock sigma factor RpoH in "Ca. Blochmannia," typical RpoH-dependent promoters were identified. However, no heat shock response resembling that of E. coli could be detected in "Ca. Blochmannia."
