Ligandfructose in medium and LevR dephosphorylation in cell (1).
CommentThe lev operon is controlled by RNA polymerase associated with sigma 54 factor and by the LevR activator that is homologous to the NifA/NtrC family of regulators(1,2). The activity of LevR is regulated by two PEP-dependent phosphorylation reactions catalysed by PTS (4).
