The arnBCADTEF operon promoter region binds FNR and arnBCADTEF expression is repressed by FNR (Federowicz, 2014). basRS regulon. arnT is required for survival in PMA-U937 human monocyte macrophage cells in culture. ArnT has a probable false positive lipoprotein prediction, 12 CM TMs predicted, Cys not conserved.
