Note(s): 1A model has been proposed in which ModE-molybdate serves as a secondary transcriptional activator of both the hyc and narXL operons, which are activated primarily by the transcriptional activators FhlA and NarL, respectively.1A model has been proposed in which ModE-molybdate serves as a secondary transcriptional activator of both the hyc and narXL operons, which are activated primarily by the transcriptional activators FhlA and NarL, respectively.
