Mutational analysis of the Chlamydia trachomatis dnaK promoter defines the optimal -35 promoter element.

Abstract excerpt

A long-standing question in the biology of the intracellular bacterium, Chlamydia, has been the structure of the promoter recognized by its RNA polymerase. The 'RNA polymerase sigma subunit paradox' refers to the difficulty reconciling the conservation between the RNA polymerases of Chlamydia and Escherichia coli, especially at the level of the promoter-recognition sigma subunit, with the general lack of homology...
