How the obligatory intracellular bacterium begins to replicate upon entry into human monocytes is poorly understood. electrophoretic mobility shift assays showed specific binding of recombinant NtrX (rNtrX) to the promoter regions of and and promoter-fusions in and expression through NtrY/NtrX and facilitates degradation of CtrA to initiate a new cycle of growth. IMPORTANCE Human monocytic… Continue reading How the obligatory intracellular bacterium begins to replicate upon entry into
